Experimental study on the mechanical properties of concrete by partial replacement of glass powder as fine aggregate: An environmental friendly approach

Generally in shops, damaged glass sheets & sheet glass cuttings are go to waste, which are not recycled at present and usually delivered to landfills for disposal. Glass powder used in concrete making leads to greener environment. Glass waste powder creates chronic environmental problems, mainly due to the inconsistency of waste glass streams. Glass is widely used in our day by day activities like in the products such as sheet glass, bottles, glassware, and vacuum tubing. Glass is an ideal material for recycling. The use of recycled glass helps in energy saving. In many research works aims to give awareness of glass recycling and save the environment. One of its significant contributions is to the construction field where the waste glass was reused for concrete production. In the current research work the properties of concrete with glass dust waste as fine aggregate were investigated. Glass dust waste was used as a partial replacement for sand at 10%, 20% and 30% of concrete mixes. Compression strength, split tensile strength and flexural strength for 7, 14 and 28 days concrete of age were compared with those of concrete made with natural fine aggregates. From this experimental work it was proven that increasing strength has been observed when replacing of glass waste powder by natural sand. (c) 2020 Elsevier Ltd. All rights reserved.
