Use of silica fume in concrete - ScienceDirect

Jan 01, 1996  The normal concrete used had 351 kg/m3 cement and the water-cement ratio was 0.43. In the silica fume concrete, the cement used was 286 kg/m3 and silica fume was 21.7 kg/m3, i. e., 65 kg/m3 cement was replaced by 21.7 kg/m3 silica fume. The total binder was 308 kg/m3. Thus, the CFS/ (C+CSF) was 0.07.

The A - Z Guide Of SILICA FUME why we use it in concrete

May 22, 2020  Since silica fume is a pozzolanic material, it reacts with calcium hydroxide. as a result of this, compressive strength of concrete increases. We know that if we use micro-silica in concrete, it densify the concrete therefore reduces the permeability of concrete. Due to low permeability, the aggressive chemical cannot penetrate the concrete in ...
