摘要
通过在普通水泥砂浆中掺入少量可再分散乳胶粉和聚丙烯纤维的方法,配制出施工和易性好、粘结强度高、抗裂性和耐候性优良的柔性粘结砂浆。分析了灰砂比、水泥标号、拌合工艺、聚合物品种和掺量、纤维品种和掺量、养护制度等对粘结砂浆性能的影响。
In order to overcome the disadvantages of traditional cement mortar,a new type of binding mortar adding by redispersible emulsion powder and polypropylene fiber has been developed.This new type of binding mortar is of high adhesive strength,good cracking re sistance,weatherability,good workability.This paper analyses the influence of cement/sand ratio,grade of cement mixing processes,variety and added quantity of polymer and fiber,curing system on binding mortar properties.
