Concrete brick with waste solar glass panels / Nulfhatin Mohd Rafail and Siti Jamiah Tun Jamil

Bricks are one of the primary materials required for building constructions. This material is widely used due to its advantages such as high durability, energy-efficient, low maintenance, and energy cost savings. The main goal of this innovation is to study the possibility of using waste solar glass panels to replace a part of the natural sand used in the production of concrete bricks. Brick specimens were prepared using sand, cement, and water, in which they were then replaced with waste solar glass panels at the percentage levels of 2% and 4%. Several series of tests were carried out to study the effect of the use of waste solar glass panels on the physical and mechanical properties of bricks. These tests include density, compressive strength, water absorption, and Ultrasonic Pulse Velocity (UPV) tests. The findings revealed that the bricks containing the waste solar glass panels share similar favourable characteristics in terms of physical and mechanical properties with bricks. The replacement of sand by waste solar glass panels at the percentage level of 2% exhibited the highest compression test results and water absorption compared to other percentages and control specimens.
