Portland pozzolana cement (PPC) is a type of eco-friendly cement which is mainly made of ordinary portland cement clinkers and pozzolanic materials (such as fly ash, calcined clay, etc.). Generally, the constituent of pozzolanic materials in Portland pozzolana cement is 10% ~ 25% by mass percentage. Fly ash is the main ash discharged from the ...

Cement is one of the most widely used substances on earth. Making cement is an energy and resource intensive process with both local and global environmental, health and safety impacts. Recognizing these facts, several cement companies, initiated the Cement Sustainability Initiative (CSI) as a member-sponsored program of the World Business Council

Finer cement offers a greater surface area for hydration and hence faster the development of strength. The fineness of grinding has increased over the years. But now it has got nearly stabilized. Different cements are ground to different fineness. The particle size fraction below 3 microns has been found to have the predominant effect on the ...
