本文总结了在20、40和60 °C温度水平下聚合物水泥砂浆（PCM）-混凝土界面和PCM覆盖钢筋混凝土（RC）梁性能的试验和分析研究。在材料层面上，通过界面劈裂拉伸强度和双面剪切强度试验对粘接性能进行了测试。在构件层面，通过对受拉面粘贴相变材料加固的钢筋混凝土梁进行四点弯曲试验，检验了粘结性能。温度对两个水平的测试都有显着影响，并且随着温度的升高，观察到强度降低。提出了材料界面强度的预测公式，并在所有温度水平下进行了验证。极限剪切载荷和失效模式的分析计算桁架模型的方法，并与实验观察。在20、40和60 °C的温度下观察到非常接近的对应关系。
This paper summarizes the experimental and analytical investigation on performance of polymer cement mortar (PCM)-concrete interfaces and PCM overlaid reinforced concrete (RC) beams at temperature level of 20, 40 and 60 °C. At material level, bonding were tested by conducting interfacial split tensile strength test and bi-surface shear strength test. At member level, bonding was tested by conducting four point bending test of RC beam strengthened by overlaying with PCM on tension faces. Temperature showed significant effects on both levels of tests and reduction in strengths were observed with increase in temperature. Prediction formulas for interfacial strengths of materials were proposed and verified at all temperature levels. Ultimate shear loads and failure modes were analytically calculated by the truss model approach and were compared with experimental observations. Very close correspondences were observed at temperature of 20, 40 and 60 °C.
