Mineral Admixtures For High Performance Concrete

Mineral Admixtures For High Performance Concrete High Performance Concrete (HPC) is the latest development in concrete It is not just High- Strength Concrete (HSC) and has replaced HSC developed in the early 1980’sMineral Admixtures - The Concrete Portal,Metakaolin has a performance comparable to silica fume as a mineral admixture in concrete Since MK is not a by-product, its processing is an expensive affair Thus the marketability of MK is not as good as silica fume, which is a proven by-productCivil Engineering: HIGH PERFORMANCE CONCRETE,11062010 · High Performance concrete works out to be economical, even though it’s initial cost is higher than that of conventional concrete because the use of High Performance concrete in construction enhances the service life of the structure and the structure
