摘　　要：研究了不同矿物掺合料对干粉砂浆流动性、保水性能和强度的影响.试验结果表明,掺加矿物掺合料对砂浆工作性能和力学性能均有所提高,其中以10%的粉煤灰,20%的矿粉复掺时,砂浆工作性能最好,抗压和抗折强度最高,28d龄期强度分别能够提高75%和25%.The paper mainly researches the influence of different mineral admixtures to liquidity, water performance and strength of dry mortar. The test results show that, adding mineral admixtures im- proved mortar working performance and mechanical properties, mortar work performance is the best when 10% of fly ash and 20% of the mineral powder with complex, compressive strength and flexural strength is the highest, 28d cement strength can be increased by 75% and 25% respectively.
