摘　　要：将花岗岩石粉按不同比例等量替代石英砂,研究了花岗岩石粉掺量对聚合物水泥防水砂浆力学性能、柔韧性及抗渗压力的影响。研究结果表明:花岗岩石粉在掺量不超过15%时,可显著提升防水砂浆的力学性能及抗渗压力,当花岗岩石粉掺量超过15%后,防水砂浆的力学性能和柔韧性下降。花岗岩石粉可应用于聚合物水泥防水砂浆中,其替代石英砂的最佳比例是15%。Influence of granite powder on the mechanical properties,flexibility and impermeable press of polymer cementitious waterproof mortar is studied through replacing the silica sand by different proportions of granite pow⁃der.The result showed that,granite powder could significantly improve the mechanical properties and imperme⁃able press of polymer cementitious waterproof mortar when the proportion of granite powder is no more than 15%.If the proportion of granite powder is more than 15%,mechanical properties and flexibility of polymer cementi⁃tious waterproof mortar decreased.Granite powder could be used in polymer cementitious waterproof mortar de⁃creased and the optimal replacement proportion of silica sand is 15%.
