Abstract The weight of the building has been increasing recently because of high-rise and enlargement of buildings. Lightweight concrete contributes to economical, by decreasing the weight of buildings and reducing the size of structure, and releasing the impact of earthquake load when it is applied to construction. Also, Lightweight concrete can be useful for noises through floor, soundproof, sound insulation facilities when it is used as structures and absorbing materials. Lightweight concrete is mainly used to lightweight aggregate concrete and lightweight foamed concrete. The property of foam in lightweight concrete shows a great difference depending on the ingredient and amount of foaming agent. To select foaming agent which is suitable for the purpose, it is essential to conduct a basic study to find the right property of bubbles. This study aims at understanding the property of foaming agent and identifying that influences of foam when mixed with cement mixture. Foaming and decreasing of foam volume test of foaming agent, the analysis of bubble shape, compressive strength test, apparent density and the percentage of air content are measured by setting water-binder ratio, the types of foaming agent, and change of concentration as factors. This leed to the comparison and analysis of physical properties of lightweight foam cement paste,
