Clinker is the main ingredient in cement and the amount used is directly proportional to the CO 2 emissions generated in cement manufacturing due to both the combustion of fuels and the decomposition of limestone in the clinker production process From 2014 to 2018 the clinkertocement ratio increased at an average of 16 per year reaching an estimated 070 in 2018 this … ... and results in the conversion of carbonates to oxides. For this denominator, the terms “cementitious products” or “binders” are used, as it is a sum of clinker and mineral components. Cement in Europe must be manufactured according to the harmonised European Standard EN 197-1, which lists 27 common cements according to their main constituents. It is produced by sintering limestone and aluminosilicate materials such as clay during the cement kiln stage. Clinker, line008:In the context of this Protocol, clinker refers to grey and white clinker used for the production of grey and white cement. Clinker can be blended with a range of alternative materials, including pozzolans, finely ground limestone and waste materials or industrial by-products. Standard cements like Portland Cement consists of more than 90% clinker. In the Cement CO2 and Energy Protocol and the “Getting the Numbers RightThe GNR (“Getting the Numbers Right” or “GCCA in NumbeRs”) is a key tool in how key sustainability progress is monitored and reported. Hence it is a virtual cement production under the assumption that all clinker produced in a plant is consumed for cement production in the same plant and applying the real plant specific clinker/cement factor. The following sections refer to the consumption and processing of mineral components. Also the industry blending ratio (i.e. bridges, sky scrapers as well as for the sustainability of investments into infrastructures and buildings. Limitation chart for w-c ratio shows the maximum value of the w-c ratio as per IS 456: 2000 which can be adopted during mix design. To ensure the future use of other constituents, the cement industry is dependent on the local supply of these materials. Please also see the Protocol Guidance Document (Chapter 6.3) and the Glossary. In addition, a strong industry focus on innovative cements and concretes has the potential to respond to the requirements of sustainable and resource-efficient production and construction. The cement sector is the third-largest industrial energy consumer and the second-largest industrial CO 2 emitter globally. The term 'cement' is used to describe a range of binding materials, the most common of which are known as hydraulic cements. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. However, ICRA said that the sharp increase is unlikely to translate … The w/c ratio is calculated from the weights of the materials, eg Concrete with 300kg of cement and 180 litres of water has a w/c ratio of 0.6 (i.e. Silica fume, a pozzolanic material and a by-product in the production of silicon or ferrosilicon alloys. cement plant using clinker (crushing plant) The project report includes Present Market Position and Expected Future Demand, Market Size, Statistics, Trends, SWOT Analysis and Forecasts. It acts as the binding agent when mixed with sand, gravel or crushed stone and water to make concrete. On this basis, it seems that the use of other constituents could be doubled. 04. The pulverized coal preparation and cement milling sections have the lowest exergy loss. The theoretical clinker content of these cements in the European Standard can vary between 5% and 95%. Cement Analysis Iea . Reducing the clinker-to-cement ratio is key to cutting the carbon impact of cement. The rotary kiln is approximately 20 to 25 feet (ft) in diameter and from 150 ft to well over 300 ft long; the kiln is set at a slight incline and rotates one to three times per minute. 180÷300 = 0.6). Cement is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles etc. Quality is crucial for building stability and, as such, a matter of public safety, e.g. sum of clinker input = sum of clinker output. 1 415 kilograms [kg] of Cement, clinker fit into 1 cubic meter 88.33556 pounds [lbs] of Cement, clinker fit into 1 cubic foot Cement, clinker weighs 1.415 gram per cubic centimeter or 1 415 kilogram per cubic meter, i.e. Please also see the Protocol Guidance Document (Chapters 7.4 and 6.4). To make this site work properly, we sometimes place small data files called cookies on your device. The GNR database is now managed by the GCCA, having transferred at the end of 2018 from the Cement Sustainability Initiative (an initiative run through the World Business Council for Sustainable Development).” database, “cement” includes all hydraulic binders that are delivered to the final customer, i.e., including all types of Portland cements, composite cements and blended cements, but excluding direct sales of pure clinker”. Limestone (finely ground), which can be added to clinker (without being heated and transformed into lime). It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. It indicates the prehydration or carbonation due to prolonged or impropercarbonation due to prolonged or improper storage of cement & clinker.storage of cement & clinker. There is also uncertainty regarding the future availability of clinker substitutes as well as the impact of environmental policy and regulation. The clinker to cement ratios given by Atmaca and Yumrutas ¸ (2014), Kapur et al. © 2020 by Global Cement and Concrete Association (GCCA) / ECRA GmbH Clinker to cement ratio - Weighted average Grey and white cement % 92AGWce: Clinker to cement ratio - Weighted average Grey and white cement equivalent % 92DGW: Clinker to cement ratio - Distribution Grey and white cement % 92DGWce: Clinker to cement ratio - Distribution Grey and white cement equivalent % cement equivalent production Cement, line020:CementA building material made by grinding clinker together with various mineral components such as gypsum, limestone, blast furnace slag, coal fly ash and natural volcanic material. The kiln is most The International Energy Agency (IEA)2 estimated that in 2005, there were around 1,215 million tonnes of material suitable for clinker substitution globally (excluding pozzolan and limestone). density of cement, clinker is equal to 1 415 kg/m³. The availability of pozzolans depends on the local situation and only a limited number of regions have access to this material for cement production. Hence, it is a virtual cement production under the assumption that all clinker produced in a plant is consumed for cement production in the same plant and applying the real plant specific clinker/cement factor. Rising global population and urbanisation patterns, coupled with infrastructure development needs, drive up the demand for cement and concrete and increase pressure to accelerate action in reducing the carbon footprint of cement production. Cement Clinker Substitution. As shown above on the diagram; the inputs and outputs of clinker and also the clinker content in the cement have been taken into account. Portland cement clinker - overview. From 2014 to 2018, the clinker-to-cement ratio increased at an average of 1.6% per year, reaching an estimated 0.70 in 2018; this rise was the main reason for the increase in direct CO 2 intensity of cement production over the period. Ordinary Portland cement can contain up to 95% clinker (the other 5% being gypsum).

This difference alone is equivalent to achieving a 30% reduction in the clinker factor. As per Emami Cement DRHP, clinker utilization in India has increased from 75% in FY14 to ~80% in FY19. The importance and relevance of these qualities depend on the desired application of the cement and concrete. In ordinary Portland cement clinker, the AR is usually between 1 and 4. Equation 10: Clinker mass balance For the clinker mass balance at plant level this means: B + S start + C in + K in + P = D + S end + C out + K out + M. where: B = the clinker which is bought from other companies. The above three parameters are those most commonly used. About Cement, clinker; 1 cubic meter of Cement, clinker weighs 1 415 kilograms [kg] 1 cubic foot of Cement, clinker weighs 88.33556 pounds [lbs] Cement, clinker weighs 1.415 gram per cubic centimeter or 1 415 kilogram per cubic meter, i.e. Over 80 percent of cement and clinker imported in 2012 came from five major countries: China, Canada, Columbia, Mexico, and the Republic of Korea. Approximately 800-900Mt/yr of clinker and cement benefit from seaborne cement and clinker trade and distribution. While cement qualities are defined by national standards, there is no worldwide, harmonized definition or standard for cement. Cement (equivalent), line021b:Cement (equivalent)Cement (equivalent) is a cement production value which is determined from clinker produced on-site applying the plant specific clinker/cement-factor. Cementitious products, line021a:Cementitious productsAll clinker produced by the reporting company for cement making or direct clinker sale, plus gypsum, limestone, CKD and all clinker substitutes consumed for blending, plus all cement substitutes. A global clinker-to-cement ratio of 78% in 2006 meant that about 550-600 million tonnes of constituents other than clinker were used. The task of entering the data on clinker and cement production is related to a mass balance which should be determined on at plant level. The denominator excludes clinker bought from third parties for the production of cement, since this clinker is already included in the inventory of the third party. Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. Finally, a life cycle cost analysis needs to be done to ensure that policies are based on the entire life cycle in order to avoid focusing solely on intermediate material impact. Advertising: Tailor information and advertising to your interests based on e.g. The use of other constituents has an impact on the way the cement will perform in both the short and long term. Recent estimates are that these so-called “process” emissions contribute about 5% of total anthropogenic CO2 emissions excluding land-use change (Boden et al., 2017). Most big websites do this too. Varying clinker content has an impact on the type of applications the cement can be used for. Mortar ratio of 1:4 to 1:8 (cement: sand, water to be judgmental), for 5 to 7 times thickness of verified tiles, should be given as bed between RCC floor and tiles. The current average clinker-to-cement ratio over all cement types in the EU27 is 73.7%1. Provide support for and access to R&D funding. Lime saturation factor (LSF) (2009) , and Low (2005) are higher than the clinker to cement ratio in this study. However, this can result in some functions no longer being available. in the Protocol refers to building materials made by grinding clinker together with various mineral components such as gypsum, limestone, blast furnace slag, coal fly ash and natural volcanic material. or the purposes of meaningful reporting, the definition of cement used in the GNR database differs slightly from that in common use. cem the fraction of clinker in cement (the “clinker ratio”), and Mcem the mass of cement (see Appendix A for details). A second way to a better understanding of the mass balance is the explanation of the mass balance equation. The clinker-to-cement ratio (percentage of clinker compared to other non-clinker components) has an impact on the properties of cement so standards determine the type and proportion of alternative main constituents that can be used. In this document, cement and cementitious products are considered equivalent. The current average clinker-to-cement ratio over all cement types in the EU27 is 73.7% 1. fraction of clinker in the cement and back-calculate clinker production. 2 Source: http://www.wbcsdcement.org/pdf/technology/Technology%20papers.pdf, 3 Source: Development of State of the Art Techniques in Cement Manufacturing: Trying to Look Ahead (CSI/ECRA- Technology Papers), State of the Art Paper No 4: Reduction of clinker content in cement: long-term perspective. The production of clinker is the main source of CO2 in cement production. The success of cements with a low clinker-to-cement ratio will also depend on market acceptance. In addition to the sales of cements, the sales of processed mineral components are summarized in line019 named ‘Total processed MIC's used as clinker or cement substitute sold externally’. produce Portland cement. Decide which cookies you want to allow. The availability of alternative materials that can be used as other constituents varies considerably. The following plant mass balance diagram will help you to obtain the requested values as required for correct calculations. Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. is a cement production value, which is determined from clinker produced on-site applying the plant specific clinker/cement-factor.

Limestone is abundant worldwide and is easily accessible to most cement plants. 2: Clinker is a granular substance containing spherical pellets of diameter 3-25 mm. Fly ash, dust-like particles from flue gases of coal-fired power stations. The terms “cementitious products” or “binders” are used, as it is a sum of clinker and mineral components. Ordinary Portland cement can contain up to 95% clinker (the other 5% being gypsum). The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. Pune: India’s cement industry saw a 13.6% year-on-year increase in volume to 275.7 million metric tonnes in the first ten months of the current fiscal, driven largely by rural and affordable housing, according to a report by credit rating agency ICRA.The growth was almost double the 7% increase forecast by the agency. TABLE 5.2 GLOBAL AND COUNTRY-SPECIFIC RATIO OF CLINKER TO CEMENT FOR BOTH SCENARIOS (SOURCE: AUTHORS, BASED ON IEA 2016A,2016E, 2015,2009,WBSCD 2014 ) Overview. the content you have visited before. 3 Typical Range : 1.0 – 1.5 Clinker with higher Alumina modulus results in cement with high early strength 4. In the "WBCSD - CSI Cement CO2 and Energy Protocol" and the "Getting the Numbers Right" database, both now managed by GCCA, "cement" includes all hydraulic binders that are delivered to the final customer, i.e., including all types of Portland, composite and blended cements, plus ground granulated slag and fly ash delivered to the concrete mixers, but excluding pure clinker. Calculate water-cement ratio from the maximum free water/cement ratio according to environmental exposure condition as per table 5 of 456-2000, this is the limitation given by Indian Standard. For example, granulated blastfurnace slag availability depends on the location and output of blastfurnaces for pig-iron production equipped with slag granulation facilities, whilst fly ash use is dependent on supply from sufficiently close coal-fired power plants. However, the rest of the specific heat consumption as tabulated above constitutes heat losses from preheater exhaust gases, clinker, cooler exhaust gases, preheater dust and radiation losses. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. Please also see the Protocol Guidance Document (Chapter 6.2) and the glossary for more details on the following definition of the products clinker, cement (equivalent) and cementitious products.Please refer to the Protocol Guidance Document (Chapter 7.4) for information on the correct accounting of internal transfers of clinker, cement and mineral components (MIC) in the Plant sheets and the Company sheet in relation to line010b, line010c, line017a and line019c. In addition to the consumption of clinker for cement production, the sum of mineral components consumed for cement production is represented in line018 named ‘Total MIC consumed for Portland and blended cements’. grinding or thermal treatment). The heart of clinker production is the rotary kiln where the pyroprocessing stage occurs. At a European level, it is estimated that the clinker-to-cement ratio can be reduced to 70%, resulting in a further CO2 saving of 4%. A fourth, the 'Lime Combination Factor' (LCF) is the same as the LSF parameter, but with the clinker free lime content subtracted from the total CaO content. Clinker Cement; 1: Clinker is a nodular material which is used as the binder in cement products. Cementitious products can therefore be described as the total of all cements and clinker produced by a cement company, excluding the clinker purchased from another company and used to make cement. Cookies Note that the denominator excludes the following: Cement volumes which are traded without any processing. These factors translate into a reduction in the CO 2 emissions during cement manufacturing, from 816 kg/t of OPC clinker to 570 kg/ t of Solidia Cement clinker. You can change these settings at any time. The overall process of conversion from raw meal to clinker being endothermic demands a theoretical heat of about 380-420 kcal/kg-clinker. This page gives a thumbnail sketch. Low-clinker cements can offer both environmental benefits as well as favourable product characteristics. Table 15.8. As shown, the use of blended cement reduced CO 2 emissions by about 20% from 1990 to 2013, and a reduction in the cement-to-clinker ratio to 71% is expected in 2050 (Table 15.8). Granulated slag and fly ash from coal fired power plants, which are stored or sold to another company without any processing for changing their properties (e.g. 1 For the purposes of meaningful reporting, the definition of cement used in the GNR database differs slightly from that in common use. So at current levels, with clinker capacity of ~293-298 MTPA and cement Reduction in CO 2 emissions through use of blended cements (WBCSD, 2013) View chapter Purchase book The second source of emissions is from the combustion Clinker bought from third parties for the production of cement is excluded here, since this clinker is already included in the inventory of the third party. For the clinker mass balance at plant level this means: B + Sstart+ Cin+ Kin+ P = D + Send+ Cout+ Kout + M. The amount of clinker consumed which is calculated in line011 in the Plant sheet can therefore be expressed by the following equation: M = P + B - D - ( Send-Sstart) + ( Cin- Cout) + ( Kin- Kout), In Plant sheet line numbers, this means: line011 = line008 + line009 - line010 - line010a + line010b + line010c. The different types of materials produced are summarised in lines020, line021, line021a and line021b. However, this scenario is only hypothetical because it does not take into account that these quantities do not necessarily reflect the required quality or local market situation3. clinker to cement conversion) has improved to 1.44x in FY19 vs 1.41x in FY16. In this document, cement and cementitious products are considered equivalent, A low-carbon European concrete and cement sector in 2050, Smart Building and Infrastructure Development, http://www.wbcsdcement.org/pdf/technology/Technology%20papers.pdf. While cement qualities are defined by national standards, there is no worldwide, harmonised definition or standard for cement. The use of other constituents in cement and the reduction of the clinker-to-cement ratio means lower emissions and lower energy use. The ability to sell cement (or clinker) in long distance markets not only brings the profits that go with the trade itself, but ensures a substantial reduction in production costs per tonne over the full production volume of the plant. Cement CO2 and Energy Protocol, Internet Manual, created 27/02/2020, © 2020 by Global Cement and Concrete Association (GCCA) / ECRA GmbH. Nevertheless, it is important that a whole life cycle approach is applied to public procurement rather than simply focusing on product footprinting or intermediate product impacts. For example, the future decarbonisation of the power sector could limit the availability of fly ash, or the application of Nitrogen Oxide(s) abatement techniques in coal-fired power stations could mean that the fly ash may be unusable as a constituent in cement due to higher NH3 (ammonia) concentrations. Moya, N. Pardo, A. Mercier Granulated blastfurnace slag (GBFS), a by-product of the pig-iron/steel production process. Natural pozzolans, such as clays, shale and certain types of sedimentary rocks. Learn more about the cookies we use. What is the history of cement? Cement clinker substitution occurs when clinker, the primary material used in cement manufacturing, is substituted with other cementitious materials, such as coal fly ash or blast furnace slag. Plant #1). Thus, high durability of the final product concrete is a key property for sustainable construction. Also, coal power preparation section has the highest recycling ratio, followed by raw material preparation with large amount of sensible heat exergy, while the clinker calcination section has a lower ratio due to coal combustion. Our ambition is to reach an average clinker factor of 68% globally by 2030, by repurposing byproducts from other industries and construction and demolition waste, investing in calcined clay facilities as well as developing novel cements with new binders. Figure 8: Schematic diagram on how to determine the clinker mass balance in a plant (e.g. The gap between domestic production and consumption was filled in 2012 by over seven million metric tons of imported cement and cement clinker. Furthermore, some of these materials are already used in concrete, rather than cement, production. Clinker occurs as lumps or nodules, usually 3 millimetres to 25 millimetres in diameter. In any kind of cement type, clinker is the major ingredient.
