Effect of Partial Replacement of Cement and Sand by Silica Fume and Stone Dust in Concrete

In the ongoing past, there have been significant endeavors for enhancing the properties of cement as for quality and toughness, particularly in forceful conditions. The improvement of solid innovation can diminish the utilization of common assets and vitality sources and lessen the weight of toxins on condition. Proper introduction of silica fume and stone-dust in concrete improves both the mechanical and durability characteristics of the concrete. A large amount of by-product or wastes such as fly-ash, copper slag, silica fume, stone-dust etc. are generated by industries, which causes environmental as well as health problems due to dumping and disposal. The waste materials which can be utilized as extra cementitious material, appropriate presentation of silica smolder in cement enhances both the mechanical and toughness qualities of the solid. This paper present literature review on replacement of Cement by Silica Fume and sand by stone-dust which includes current and future trends of research.
