承台挡土墙预制板用原状稻壳砂浆的力学性能研究
Study on Mechanical Properties of Undisturbed Rice Husk Mortar for Prefabricated Retaining Wall of Cap
摘要
Abstract
To explore the feasibility of using rice husk,an agricultural waste,for preparing light-weight and high strength building materials,the original rice husk mortar was made by using the original rice husk instead of the engineering sand,mixed with polypropylene fiber with different blending ratio and length,and made with cement and water.We analyzed the influence of replacing part of engineering sand with original rice husk on the properties of mortar through experiments.The compressive strength,flex-ural strength and density of rice husk mortar were studied through macroscopic experimental studies.The re-sults showed that the proper addition of rice husk could improve the compressive and flexural strength and reduce the density of the mortar compared with the original mortar.The 28 d compressive and folding strengths of rice husk mortar with a rice husk content of 40%and polypropylene(PP)fiber content of 0.1%and the PP fiber length of 6 mm were the highest,which were 9.61 MPa and 2.45 MPa,respectively.The order of the influence of each factor was as follows:rice husk content＞fiber length＞fiber volume.关键词
