摘　　要：研究针对微膨胀剂在公共建筑地下室防水混凝土中的应用和对其性能的影响进行了分析。研究拟采用试验与理论相结合的方式,对微膨胀剂提高抗渗性能的机理进行深入探究。通过对不同掺量的微膨胀剂进行比较试验,研究了微膨胀剂对混凝土工作、力学和抗渗性能的影响。最终得出,在地下室中加入适量的膨润土,可有效减小混凝土的干缩裂纹,改善其强度、抗渗能力,其对地下室防水混凝土的综合性能有明显的改善。通过进一步优化微膨胀剂的用量,为其在工程中的应用奠定基础。The study analyzed the application of micro expansion agents in waterproof concrete for public building basements and their impact on their performance.The research intends to use a combination of experimental and theoretical methods to conduct in-depth exploration of the mechanism by which micro expansion agents improve impermeability performance.By conducting comparative experiments on micro expansion agents with different dosages,the effects of micro expansion agents on the workability,mechanics,and impermeability of concrete were studied.Finally,it was found that adding an appropriate amount of bentonite to the basement can effectively reduce the shrinkage cracks of concrete,improve its strength and impermeability,and significantly improve the comprehensive performance of basement waterproof concrete.By further optimizing the dosage of micro expansion agent,a foundation is laid for its application in engineering.
