Properties of Foamed Concrete According to Concentrations of Synthetic Type Foaming Agents

합성 기포제 희석 농도에 따른 기포콘크리트의 특성

Pre-foaming that has been used in this study is using to control and guarantee quality, but the optimum mix proportion and regulation are not definite. Therefore, this study investigated properties of foamed concrete according to concentrations of foaming agent to improve usability of foamed concrete. Synthetic foaming agent such as AES(Alkyl Ether Sulfate) and AOS(Alpha Olefin Sulfonate) are used to make foam with 1, 3, and 5% concentrations. We found that the flow of foam concrete increases when foam concentration is high and AES is more flowable than AOS. Density and compressive strength increase when foam concentration is low.
