Synthesis of Compound Foaming Agent of Lightweight Foamed Concrete

The foaming agent used in lightweight gypsum-based foam concrete was discussed. The effect of the single-doped foaming agent, codoped foaming agent and ternary foaming agent on the settling height, bleeding volume and defoaming time of fresh foam were investigated. The results show that ternary foaming agent has potential synergistic effects for reducing settling height and bleeding volume and retarding defoaming time of fresh foam. While applying this new compound foaming agent to the manufacture of the lightweight foam concrete blocks, samples with better-performance were obtained.
