Abstract

One of the methods used to reduce the weight of a construction is by reducing the weight of the walls of the building. In such a case, a wall made of red brick has a volume weight of 1,500–2,000 kg/m3, and concrete masonry bricks made of CLC have a volume weight of 400–900 kg/m3. So, in comparison, concrete masonry bricks have a volume weight that is ≤ 50% of that of red brick. In the manufacturing of concrete masonry bricks, one variant is CLC (Cellular Lightweight Concrete), produced using a mixture of cement, sand, chemical admixture and water, with the filler material in the form of air generated as microscale soap bubbles (microbubbles), also known as foam agent. In the manufacturing of concrete masonry bricks, the mineral admixture as a filler material clearly affects the physical and mechanical properties of the bricks produced. This research is conducted to investigate the effect of the amount or composition of the mineral admixture (gypsum) on the physical and mechanical properties of concrete masonry bricks. The composition is varied among 15 kg/m3, 30 kg/m3, 60 kg/m3, 75 kg/m3 and 120 kg/m3 of gypsum in the making of CLC masonry concrete brick.
