Abstract
Concrete is one of the most widely used construction materials in the world. However, the production of Portland cement, an essential constituent of concrete, leads to the release of significant amount of CO2, a greenhouse gas. One ton of Portland cement clinker production is said to create approximately one ton of CO2 and other greenhouse gases (GHGs). Environmental issues are playing an important role in the sustainable development of the cement and concrete industry. In order to address environmental effects associated with cement manufacturing, there is a need to develop alternative binders to make concrete. Storage and safe disposal of waste & crushed glass is a huge problem for our urban & rural areas in India. Everywhere reuse of waste glass eliminates this problem. In this experimental work, the effect of partially replacing of glass powder in concrete is studied. The cement in concrete is replaced by waste glass powder (WGP) in steps of 0%,5% ,10% &15% respectively by volume of cement and its effects on compressive strength, split tensile strength, workability and flexural strength are determined at 7th, 28th and 45th days. It is found that the compressive, flexural and split tensile strengths of concrete increase initially as the replacement percentage of cement by glass powder increases and becomes maximum at about 10% and later decreases. The workability of concrete reduces monotonically as the replacement percentage of cement by glass powder increases. The replacement of cement up to about 10% by glass powder can be done without sacrificing the compressive strength
