摘要：

A test was carried out to study the interface shear strength between carbonated concrete substrate and self-compacting concrete (SCC) overlay. One hundred and fourteen Z-type specimens were designed and subjected to direct shear tests. The influence of four interface treatment methods, three strengthening schemes and SCC strength on interface shear strength were discussed. Two coefficients considering the influence of interface treatment method and strengthening scheme on interface shear strength between carbonated concrete and SCC were developed. The results show that interface shear strength...
