对泡沫水泥新材料进行了系列配方试验,研制出适用于井下冒落空洞充填等用途泡沫水泥新配方,分析了水泥品种、泡沫剂、促凝剂、稳泡剂等因素对制备泡沫水泥的影响。根据实验结果和用扫描电镜对泡沫材料微观形态的观察结果,提出稳泡剂应具有的分子结构特性。介绍了新材料的主要技术性能参数。
A series of formula experiments were carried out on the new material of foam cement to develop a new formula of foam cement suitable for underground filling and cavity filling. The influence of cement varieties, foaming agent, coagulant and foam stabilizer on the foam cement was analyzed . According to the experimental results and the SEM observation of the microscopic morphology of the foam, the structural characteristics of the foam stabilizer should be proposed. The main technical performance parameters of the new material are introduced.
