Abstract

In the building of ceilings, foam mortar can be utilized instead of cement board. This lightweight material may make installation and maintenance easier for users. This study aimed to determine the physical and mechanical properties of lightly foamed cement boards, investigate the influence of admixture on flexural strength, and determine the effect of admixture on flexural strength. The research method used is an experimental method by making cement board test objects. As an independent variable the composition of the mixture with a ratio of 1 Cement: 1.2 Sand: 0.47 phase, with a mortar ratio of 0.45: 0.55; 31% glass fiber and 1:30 foam agent as well as 6 different admixture variations, namely 0%, 0.2%; 0.4%; 0.6%, 0.8% and 1.0%. The dependent variable consists of density, specific gravity, nailing ability, and flexural strength. The results showed that the higher the admixture content, the easier the fresh foam mortar mix to work with. For the ability to nail all cement boards, it does not split and there are no surface cracks, and also the nails are easy to pull out. The density value tends to decrease from 0.902 to 0.719 and for specific gravity, it decreases from 0.944 to 0.749. The value of flexural strength tends to increase and the optimum value is obtained at 0.8% admixture variation of 60.44kg/cm2. The lightweight foamed cement board still meets the specifications and this lightweight foam mortar mix can be used as an alternative to the lightweight foamed cement board for ceilings.
