Experiment on concrete with partial replacement of sand with alternate green materials

Abstract

In recent decades, there is a sprut in the growth of the construction industry. Aggregates are one of the main ingredients for making concrete. Depletion of natural resources of sand and the effect of mass production of cement on sustainable environment, need studies on the use of alternative materials. On the other hand, dumping of wastes from the industries are piling up resulting in the pollution of the environment. By considering the above facts, severe studies are focused on partial replacement of river sand with alternatives like copper slag, steel slag, quarry dust, etc., The outcome of these studies shows that the alternate materials enlarge the mechanical and durability properties of concrete. The optimum dose of alternate materials to replacement of sand is evaluated. In this paper, technical papers published by researchers are studied, discussed and scompared.
