Abstract :
Concrete can bear up the severest environmental conditions; however, in several conditions it may show very low characteristics. Hence, engineers worldwide are constantly trying to improve its characteristics with the aid of modern admixtures and waste materials, usually called as alternate building materials (ABM). Currently, concrete mixtures include different alternate building materials which produce part of the cementitious constituent. The major advantage of ABM is its capacity to substitute basic ingredients partially or wholly in concrete and still presenting the cementitious property. The use of waste material as ABM helps to consume these waste materials and also improves the properties of concrete in fresh and hydrated states. Most significant ABMs which are used very frequently are fly ash and silica fume as they enhance both compressive strength and durability of concrete. This paper reviewed several researches performed to observed the affect of using silica fume in conc
