摘　　要：为了改善混凝土抗渗性,采用多元矿物外加剂、聚丙烯纤维与引气剂组合复掺配制混凝土,并进行了混凝土渗透性试验.结果表明:多元矿物外加剂复掺,可有效提高混凝土的抗渗性;而多元矿物外加剂分别与一定量聚丙烯纤维和引气剂复掺,可使混凝土抗渗性得到进一步改善,且随着聚丙烯纤维和引气剂掺量在一定范围内的增加,混凝土抗渗性的改善程度愈加明显.In order to improve the impermeability of concrete, we make concrete with admixture composition including multiple mineral admixtures, polypropylene fiber and air entraining agent, and test the impermeability of concrete. Results show that multiple mineral admixtures can improve the impermeability of concrete effectively, composition of multiple mineral admixtures with different quantities of polypropylene fiber can further improve the impermeability of concrete, and the impermeability of concrete improves more obviously with the increase of amount of admixture of polypropylene fiber and air entraining agent.
