Abstract
In recent years significant attention has been given to the use of pozzolan silica fume as a concrete property-enhancing material, as a partial replacement for portland cement, or both. The initial interest in the use of silica fume was mainly caused by the strict enforcement of air pollution control measures in various countries to stop release of the material into the atmosphere. More recently, the availability of high range water-reducing admixtures (HRWRA) has opened up new possibilities for the use of silica fume as part of the cementing material in concrete to produce very high strength or very high levels of durability or both. In this study effective use of silica fume as cementitious material in making high performance concrete has been studied as a result of which the air pollution due to silica fume can be minimized. It is vital to minimize air pollution and to enjoy the pollution free environment because air is one of the important resources for the sustenance of life on terrestrial organisms.
