    Jun 14, 2018 ABSTRACT: Appropriate presentation of silica fume in concrete enhances both the mechanical and durability qualities of the solid. The long-term compressive quality of silica-rage concrete has been as of late addressed by a few specialists. This reports the consequences of compressive quality information on 4-to 6-year-old centers acquired from very much archived field

    Sep 28, 2020 Sep 28, 2020 Silica fume is a byproduct from the production of elemental silicon or alloys containing silicon in electric arc furnaces. At a high temperature of 2000 o C (approx) the reduction of high-purity quartz to silicon produces silicon dioxide vapor, which condenses at low temperatures and oxidizes to produce silica fume.. Silica fume particles are spherically shaped and very fine, having a
