Foam concrete and preparation method thereof
The invention discloses foam concrete and a preparation method thereof. The foam concrete comprises cement, fly ash, water, a water reducing agent, a foaming agent, a foam stabilizer and a bubble control agent. The bubble control agent is prepared by mixing a water-based pressure-sensitive adhesive and a temperature-sensitive adhesive, wherein the phase change temperature of the temperature-sensitive adhesive is controlled to be 20-30 DEG C; the foaming agent is hydrogen peroxide. Through the temperature sensitivity and pressure sensitivity effects of the bubble control agent in the foaming process, control over the bubble volume is achieved, and generation of communicating pores is avoided; hydrogen peroxide serves as a foaming agent, the effect of controlling the bubble volume is achieved through the pressure-sensitive adhesive and the temperature-sensitive adhesive, bubbles are controlled to be further expanded through the pressure-sensitive adhesive in the bubble increasing process, and the bubble volume is controlled through the temperature-sensitive adhesive; by adopting the proportion, the strength of the foam concrete can be improved, and the water absorption rate and the heat conductivity coefficient of the foam concrete can be reduced.
本发明公开了一种泡沫混凝土及其制备方法。本发明所述泡沫混凝土包括水泥、粉煤灰、水、减水剂、发泡剂、稳泡剂及气泡控制剂；所述气泡控制剂由水性压敏胶和温敏胶混合制备而成，其中温敏胶相变温度控制在20～30℃；所述发泡剂为双氧水。本发明通过气泡控制剂在发泡过程中的温度敏感和压力敏感作用，实现了对气泡体积的控制，避免连通孔隙的产生；以双氧水为发泡剂，通过压敏胶和温敏胶起到控制气泡体积的作用，在气泡增大过程中通过压敏胶控制气泡进一步扩大，通过温敏胶控制气泡体积；采用本发明所述配比能够提高泡沫混凝土强度，降低其吸水率和导热系数。
