EFFECT OF GLASS POWDER ON COMPRESSIVE STRENGTH AND FLEXURAL STRENGTH OF CEMENT MORTAR

The glass is widely used and least recycled material in the country like India. Glass being non-biodegradable, landfills do not provide the proper solution in the waste management. So among the various ways in utilizing the waste glass is in concrete industry. This paper studies the utilization of glass in the form of powder by partially replacing the cement in cement/sand mortar. For this purpose, mortar cubes were prepared to replace cement with glass powder ranging from 0 to 30% at 5% interval and tested for mechanical properties. Similarly, reinforced concrete beams of grade M30 were casted and the beams were laminated with ferrocement. In the ferrocement jacket, cement was replaced partially with glass powder by 0%, 5% and 10% and test were conducted to replicate the effect of glass powder in compression and flexure. The test result showed the optimum compressive strength at 10% glass powder at all the testing days. The workability of the mortar mix increased with increase in glass powder percentage. Likewise, the ferrocement jacketed beam with 10% glass powder showed the least deflection compared to other beams at same loading.
