Re Usage Of Waste Foundry Sand In High Strength Concrete

Economical and Crack-Free High Performance Concrete

Economical and Crack-Free High Performance Concrete Abstract HPC is typically characterized by high binder content. The binder is composed of cement and in some cases supplementary cementitious materials (SCMs) and/or fillers. High binder content is necessary to ensure high strength and durability. In case of highly flowable HPC, such as self-
