Concrete With Limestone Calcined Clay Cement | Concrete ...
Cement is normally made from Limestone, Silica, Alumina and Gypsum, but when all these ingredients are mixed at a temperature of 1500o C, it causes an emission of CO2 on environment. To reduce this, the researchers found that the use of clinker should be reduced. And here the answer is Limestone Calcined clay cement.
