Abstract
The ratio of the amount of water to cement (w/C) serves as the main factor that regulates the physical behavior of a cement-based material mixture, therefore two different foam concrete design mixes were prepared in this research. The physical behaviors of foam concrete related to both freshly mixed foam concrete and hardened foam concrete were studied, indicating a stable foam to be blended with the mortar-based cement of Portland composite cement and Polyolefin Fiber, resulting in fresh foam concrete flowing uniformly. Likewise, the results of compaction indicated that the fresh foam concrete was capable of properly compacting in the cylinder mold without the help of vibration efforts, in which higher number of w/C caused the bigger flow in diameter of fresh foam concrete compared to the mix with lower w/C. In sum, foam concrete with lower w/C presented higher compressive strength and modulus of elasticity.
