| 摘 要： | 本文研究了HEA-JL型抗裂防水剂掺量对新旧混凝土界面结合状态的影响，运用拉拔强度、劈裂强度和抗折强度多种方式评价新旧混凝土界面结合状态,并借助显微硬度仪对试验结果进行验证和分析，研究表明，抗裂防水剂的掺量为6%时界面结合紧密，界面强度高，有利于防水抗渗。

| Abstract: | The influence of anti-cracking and water-proofing admixture on the interfacial bonds between new and old concretes is presented. The pull-off test, spitting and bending tests were conducted to evaluate the bonding states between new and old concretes. The micro-hardness in the vicinity of the interfaces was also adopted to explain the experimental results. The results showed the strongest interracial bond could be achieved when 6 % admixture was used. |

| Keywords: | anti-cracking and water-proofing admixture inter-facial bond strength pull-off strength micro-hardness |
