摘　　要：探讨硅烷偶联剂溶液浓度及其浸泡花岗岩粗骨料的时间对混凝土抗压强度的影响.结果表明,0.5%浓度的偶联剂溶液和15min的骨料浸泡时间使混凝土强度提高幅度最大.为研发中等强度、耐久性良好的混凝土提供了一条新线索.The influence of the consistency of silane coupling agent solution and the steeped period of granite aggregates on the compression strength of concrete was studied. Research results showed that the modified concrete with a solution consistency of 0.5% and a steeped period of 15 minutes obtained the most significant increase in compression strength. A new clue, thus, is provided for producing mid-strength and durable concrete.
