WATER-CEMENT RATIO LAW AND SILICA FUME

2015-7-7  The only cementitious material was cement and the largest single factor that governed the strength of concrete was the water-cement ratio. The application of condensed silica fume as a mineral admixture in concrete is almost a routine nowadays for the production of tailor made High Performance Concretes. Hence the water-cementitious material ...
