聚丙烯酸酯乳液在水泥砂浆中的应用
APPLICATION OF POLYACRYLIC ESTER LATEX TO CEMENT MORTAR
摘要
Abstract
In order to improve the toughness of cement mortar, polyacrylic ester (PAE) latex, which can form a flexible film structure, was used. The influence of the PAE latex on the bulk density, compressive strength, flexural strength, toughness, dynamic elastic modulus and tensile bond strength of the cement mortar was studied. The experimental results show that PAE latex decreases the bulk density and the compressive strength of cement mortar markedly, but only slightly decreases the flexural strength, and thus improves the toughness significantly; it also increases the tensile bond strength. The ratio of the compressive strength to the flexural strength of PAE latex-modified mortar mixed-cured for 28 d decreases to below 3 with the polymer/cement ratio (mp/mc) higher than 5%, whereas when the mp/mc is higher than 10%, the tensile bond strength of mortar is increased markedly.关键词
