Title: Recycling of glass waste as fine aggregate in concrete

Abstract

The concrete is the second most consuming material after the water on the earth. It largely contains the aggregates like fine and coarse aggregates. However, more consumption of fine aggregate could result in the depletion of natural resources. Therefore, this study considered glass waste as fine aggregate in concrete. The glass waste was collected from junkyard then grinded manually and converted into the fine aggregate. It was initially sieved through 4.75mm sieve. Afterward, different series of concrete mixes were prepared with different percentage replacement like 0%, 10%, 20% and 30% by the weight of fine aggregate. The concrete samples were cured in water tank for the period of 7 and 28days then tested for the compressive and tensile strength performances. It was observed through the laboratory findings that the 20% replacement gives the optimum performance. It was noticed that around 25% increment in compressive strength at 28days. This study indicated that the recycling of glass waste in concrete could give the better performance and solve the waste handling, environmental issues related to the glass waste.
