摘要
聚合物砂浆是加固的重要材料。对不同掺水率、不同养护龄期的聚合物砂浆试块和不同养护龄期的普通砂浆试块进行抗折、抗压试验,分析聚合物砂浆的强度发展规律。研究结果表明:龄期和掺水率都会影响聚合物砂浆的强度发展规律;与普通砂浆相比,聚合物砂浆自身黏聚性好,早龄期强度高。
Polymer mortar is an important reinforcement material.The flexural and compressive tests of polymer mortar with different water content,different curing age and common mortar with different curing age are carried out,and the strength development law of polymer mortar is analyzed.The results show that both age and water content can affect the strength development of polymer mortar.Compared with ordinary mortar,polymer mortar has better cohesion and higher early age strength.
