Abstract

Glass bottle waste takes a million years to decompose. Recycling is the best option to solve this problem. One<br />alternative is to use recycled glass in the form of powder as a material for making concrete. This study proposes the<br />use of recycled glass powder as a concrete material to partially substitute fine aggregate. This study aims to<br />determine the effect of glass powder as a partial substitute for fine aggregate on the compressive strength of concrete.<br />Partial substitution of fine aggregate was selected with a percentage of 5%, 10%, and 15%. Standard cylindrical<br />specimens aged 28 days used in compressive strength testing in this study. Then, the test results of concrete<br />containing recycled glass powder compared to ordinary concrete. The test results show that the compressive strength<br />of concrete containing 15% recycled glass powder gives an average compressive strength of 35.57 MPa which is<br />slightly higher than the compressive strength of normal concrete of 35.10 MPa. This study found that the use of glass<br />powder as a substitute for fine aggregate can be used as a substitute for normal concrete in terms of compressive<br />strength and reduce glass waste.
