Self-compactingconcrete(SCC) is a typeof concretethat is produced without compaction effort in the formwork. It settles by its own weight without any bleeding and segregation and behaves cohesively enough [1]. Theuseof SCC is believed to provide various advantages such as reduced construction time, labour costs and noise pollution as well as the easy filling of congested and thin sections.

Cementis typically made fromlimestoneand clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
