摘　　要：为揭示糯米浆三合土的物理力学性能,在同一配比的三合土中分别加入浓度0%,3%,5%,10%的糯米浆,在自然条件下养护至规定龄期(28 d,56 d,90 d)后,对其抗压强度、劈裂抗拉强度和表面硬度进行试验研究,结果表明在相同龄期条件下,与普通三合土相比,糯米浆三合土的抗压强度、劈裂抗拉强度、表面硬度均有所提高,在糯米浆浓度接近5%时,各项测试结果达到极值。In this paper, the physical and mechanical properties of sticky rice-lime mortar were investigated. Sticky rice solution, with the concentrations of 0%, 3%, 5% and 10%, was added into the cement mortar with the same mix proportion. The compressive strength, splitting tensile strength, and surface hardness were tested at required ages （28d, 56d, and 90d ） respectively under natural curing. Results show that properties of compressive strength, splitting tensile strength, surface hardness of sticky rice-lime mortar are much better than those of the blank sample at the same age. Moreover, the motor with the concentration of about 5% achieves the best performance.
