Abstract
Many piles of waste materials in this world disturb the environment. This is because
there are waste materials that cannot be disposed of perfectly, and the cost of disposing
of them is high especially glass waste. Using waste materials can reduce water, soil,
air pollution, and garbage disposal issues. This study aims to solve the environmental
problem caused by glass waste that is not disposed of by replacing glass waste as a
material in manufacturing cement bricks. The use of glass waste in building materials
has long been introduced and has proven its effectiveness. This study examines the
effectiveness of glass waste as a replacement for soil in manufacturing cement bricks.
Cement bricks will be made by replacing the natural sand with 10%, 20%, and 30% of
glass waste that is different in size from the crushed glass waste, which is 0.5cm,
1.0cm, and 2.0cm. The study results show that the value of compressive strength
increases when the percentage of waste glass increases in the brick mix. However,
compressive strength reached the maximum value at 1.0cm waste glass size (23.67
MPa) compared to 0.5cm waste glass size, 2.0cm, and control brick (6.76 MPa). It also
shows the increasing in compressive strength compared to the conventional brick
(8.01MPa). The performance of the bricks increased as the water absorption test
showed a decreasing trend as the percentage of waste glass added increased. This is
one of the studies on cement bricks for measures to reduce the disposal of glass waste
in open areas.
