Influence of Material Composition on Unconfined Compressive Strength and Elastic Modulus of Foam Concrete
Foam concrete is widely used in lightweight construction due to its low density and high insulation capacity. This study aims to investigate the impact of varying material compositions on the compressive strength of foam concrete, focusing on sand type and curing age. The objective is to optimize its strength characteristics, particularly unconfined compressive strength, for structural applications. The research methodology involves preparing foam concrete samples using two types of sand—Cimalaka and Galunggung—by varying the mix ratios of cement, water, sand, and foam agent. These samples were subjected to unconfined compressive strength tests at different curing periods, specifically.
3, 7, and 14 days, to observe strength development over time. Results reveal that both sand types, when mixed in optimal proportions, can achieve compressive strength values exceeding 800 kPa, with Cimalaka sand yielding 990 kPa and Galunggung sand reaching 1000 kPa at 14 days. Additionally, increasing the curing age significantly enhances compressive strength, and a higher cement ratio contributes to a greater modulus of elasticity, making the foam concrete stiffer and less prone to deformation. This research provides valuable insights for improving the performance of foam concrete in construction applications.
