摘　　要：为研究早强剂和增稠剂对水泥基灌浆料性能的影响,对两种外加剂不同掺量的灌浆料作配比试验。研究了两种外加剂对其工作性能、力学性能等的影响;探讨了满足技术要求的合理掺量和最佳掺量。试验证明,化学外加剂对灌浆料性能起着重要作用。In order to study the influence of early strength agent and thickener on the performance of the grouting materials,the ratio test for grouting materials of two admixtures with different amounts was conducted and the influences of two admixtures on its work performance and mechanical properties was studied.The reasonable and optimum amounts of admixture for meeting the technical requirements were discussed.The test result shows that the chemical admixtures play an important role in the performance of the grouting materials.

关 键 词：水泥基灌浆料 早强剂 增稠剂 流动性 力学性能
