Sulphate Resisting Portland Cement is a type of Portland cement in which the amount of Tricalcium aluminate (C3A) is restricted to lower than 5 % and (2 C3A + C4AF) is lower than 25%. SRC can be used for structural concrete wherever OPC or PPC or...
PPC has 80 per cent clinker, 15 per cent Pozzalona and 5 per cent gypsum and accounts for 18 per cent of the total cement consumption. It is manufactured because it uses fly ashburnt claycoal waste as the main ingredient....
Cement manufacturing is an energy intensive process. By improving the energy efficiency in terms of thermal and electric energy, it is possible to improve the bottomline by cost optimisation. In a cement kiln, 22.5% energy input is lost to the...
