SAND BRICK USING CRUSHED WASTE GLASS TO REPLACE SAND PARTIALLY

Abstract

The making of a sand brick using crushed waste glass is to recycle the waste material such as glass to replace partial sand in sand brick. This project focuses on the waste material in the production of sand brick to go eco-friendlier, cheaper, and strong. The substitution of waste glass as the sand in the sand brick is based on the problem that occurs which is objects from glass will no longer be used and cause increased waste. The main material for making this sand brick is cement, crushed waste glass, sand, and water using the ratio of (1:1:6) composition of (water: cement: sand). The waste glass will be crushed and added into the mixture of sand brick with amounts of 5%, 15%, and 25% and it will be molded into a size 200x 100x 60 mm for 24 samples. It will have dried for 24 hours and cured for 7, 14, and 21 days. The final product will be run with several laboratory tests such as a crushing strength test and water absorption test to determine its strength and ability. The test result of each sample will be evaluated and analyzed based on the standard for sand brick which is BS 6073. Thus, we gained the best average value of crushed waste glass from the compressive strength test which is 14.8N/mm² from the sand brick that contains 5% of crushed waste glass. For the water absorbing test, the best average percentage that we obtained which is the lowest percentage that sand brick absorb is 7.93% which is also the sand brick that contains 5% of crushed waste glass. In conclusion, all the data on the sand bricks that we obtained in the test passed the standard normal sand brick value especially 5% of crushed waste glass in the sand brick is categorized as a highquality sand brick.
