| 中文摘要: |
| 以丙乳砂浆、硅粉砂浆、高强砂浆、纤维高强砂浆为修复材料,以硅粉净浆及丙乳净浆为粘结剂.进行了各修复材料抗拉粘结强度、弯拉粘结强度以及修复砂浆与老混凝土的劈裂抗拉粘结强度的试验研究.研究结果表明:丙乳净浆及硅粉净浆作粘结荆能显著提高各种修复材料的粘结性能;相比于空白样,加入丙乳、硅粉、高效减水剂等外加剂后有效提高了砂浆的粘结强度;各修复砂浆28 d新老砂浆抗拉粘结强度及弯拉粘结强度都没有超过养护28 d的本体抗拉、抗折强度;从数值上看,各修复砂浆中硅粉砂浆具有最高的粘结强度.在高强砂浆配合比的基础上加入聚丙 |

| The tensile and flexural bond strength of repairing mortar and split binding strength between repairing mortar and repaired concrete were studied with acrylic acid latex mortar,silica mortar,high strength mortar,polypropylene fiber high strength mortar and basalt fiber high strength mortar as repairing mortar and acrylic acid latex paste and silica fume paste as bond agent. The results show that bond agent of acrylic acid latex and silica fume paste can improve significantly binding strength of all repairin... |
