Impact of illegal sand mining and partial replacement of sand with waste glass powder

ABSTRACT Glass is amorphous material and inert in nature which can be recycled without altering its properties. It mainly consist of silica therefore it behave like pozzolanic material and can be used as sand.Sand is major constituent of construction which led to rapid growth in its demand. This rapid demand led to illegal mining of sand which is major threat to aquatic life and hydrological change. In world, concreting is done on mass level. In searching for the substitute ,glass contribute major percentage in solid waste because of its pozzolanic behaviour and major composition of silica, it can be used in concrete. The main pretension of this study to observe the physical properties of concrete with partial replacement of waste sand in different percentage. Test conducted for study are compressive strength test and workability test at 0%,5%,10%,15%and 20% replacement of sand. KEYWORDS:-partial replacement of sand, waste glass, glass powder, illegal sand mining.
