为研究稻壳对砂浆性能的影响,分别用不同掺量稻壳等体积替代沙子制备标准试块,测定抗压强度、抗折强度和导热系数。结果表明:能提高砂浆强度,稻壳掺量为45%,抗压强度和抗折强度最大;微观分析表明稻壳表面凹凸不平的特性有助于增强稻壳与水泥水化产物的紧密黏结,使稻壳砂浆强度有一定提高;稻壳的掺入降低砂浆导热系数,稻壳掺量为50%时导热系数最小。

This paper explores the effects of rice hull on mortar .Different dosage of rice hull replacing the same vol-ume of sand preparation of standard test pieces to test the compressive strength and rupture strength and thermal conductivity .The result is that the rice hull can improve the strength and 45%is especially obvious;microscopic analysis shows that the characteristics of rice husk uneven surface can enhance the bond of rice husk and cement hydration products , improving the strength of rice husk mortar; the rice hull can re...
