摘　　要：通过研究不同掺量的矿物掺合料(粉煤灰、硅灰、矿粉)单掺和复掺对高性能水泥基材料工作性能、力学性能及其作用规律的影响,优化得到了一种强度高、工作性能好且具有一定膨胀的掺超细粉水泥基材料。试验结果表明:单掺时,粉煤灰、矿粉及硅灰的掺量分别为15%、20%、5%,可以得到较好的流动度和较高的力学性能;复掺20%的矿粉和5%的硅灰能得到较好的工作性能和较高的力学性能。By studying the effects of different admixtures of mineral admixtures (fly ash, slag powder, silica fume) on the work performance, mechanical properties and its action law of high performance cement-based materials, optimized to obtain a high-strength, high-performance of superfine powder-based cement-based material is oprimized. The test results show that the blending amount of fly ash, slag powder and silica fume is 15%, 20% and 5%, respectively, which can obtain better mechanical properties with higher fluidity;20% slag powder and 5% silica fume are compounded can get better working performance and higher mechanical properties.
