Experimental Investigation on Partial Replacement of Cement by Waste Glass Powder

All over the world million tons of waste glass is being generated. There are many forms of glass including container glass and flat glass. In day to day life glass is used in many form. It has a limited life span and after use it is either stock piled or sent to landfills. Normally waste glass does not create any harm to the environment due to its non-degradable nature but if it is improperly disposed then it may harm both human and animal. Hence, there is strong need to utilize waste glass powder. Towards the development of the sustainable (energy efficient, environmentally friendly and economical) infrastructure system, using waste glass powder as partial replacement of cement in concrete could be one of the most important step. When waste glass is converted into micro size particle it undergo pozzolanic reaction with cement hydrates, forming calcium silicate hydrate. This research work investigate the mechanical properties; compressive strength and flexure strength of concrete using waste glass powder as partial replacement of cement. To calculate the strength and other properties some number of cubes were cast using glass powder as replacement of cement at various proportions like 5 %, 10 % and 15 %. later the casted specimen are tested for its strength. Basically cement is a factory made product and their quality and standard can be easily controlled and maintained, water used is usually a tap water. Fine aggregate are natural sand.
