Abstract

Objective: To find out compressive strength, flexural strength and tensile strength of concrete by using waste glass as a fine aggregate and to check internal structure of concrete by SEM test and XRD test. Method: Waste glass is the better idea to use in concrete as fine aggregate as India produce 22 million metric ton of waste glass per year and recycles only 45% of it. Fine aggregates replaced by glass with 3%, 6%, 9%, 12%, 15% in M40 mix. In this research also alccofine 1203 used to provide additional strength to concrete. Tests performed on these examples were: compressive strength, split tensile strength, flexural strength test, SEM and XRD test. Findings: Strength increases with the addition of glass particles to the concrete by partially replacing fine aggregates. Alccofine addition to glass as additive helps to improve the strength properties of glass concrete due to its micro size. Strength increases as replacement of 5%, 7% to 9 % due to angular shape of glass molecules. Improvement: Size of the waste glass can be finer and more Alccofine may be added.
