Nodules de clinker incandescent à la sortie du four Le clinker est un constituant du ciment, qui résulte de la cuisson à très haute température d'un mélange composé d'environ 80 % de calcaire (CaCO 3 qui apporte l'oxyde de calcium, CaO) et de 20 % d'aluminosilicates (essentiellement des argiles : phyllosilicates) qui apportent les oxydes de silicium (SiO Cement clinker is a solid material produced in the manufacture of portland cement as an intermediary product Clinker occurs as lumps or nodules, usually 3 millimetres (012 in) to 25 millimetres (098 in) in diameter It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicateCement clinker

Laying the foundation for zerocarbon cement
A shift to less carbonintensive alternative fuels, such as waste and biomass, for heating kilns could decrease direct CO 2 emissions from global cement production by 9 percent by 2050 However, the Solidia, a US firm now in a partnership with major cement producer LafargeHolcim, claims that its lowclinkercontent CO 2cured concrete reduces CO 2 emissions by 70 per cent compared with OPC 83 LafargeHolcim itself has developed Aether, a belite ye’elimiteferrite (BYF) clinker that has a lower limestone content than 1 Introduction Chatham House International Affairs Think Tank

ESSD Global CO2 emissions from cement production, 1928–2018
The most recent estimate currently available from EDGAR is for 2015, at 144 Gt CO2, in very good agreement with my estimate for the same year of 143±011 Gt CO2 Cumulative emissions over 1928–2018 were 383±24 Gt CO2, 71 % of which have occurred since 1990The two broad options to decrease cement carbon intensity are (i) decreasing the carbon intensity of clinker production 9 and (ii) reducing the “clinker ratio” or proportion of clinker in cement, by substituting clinker with lowcarbon alternative constituents of cement such as blast furnace slag or fly ash 10 Producers can also reduce their own emissions locally Solving the clinker dilemma with hybrid outputbased allocation
