Abstract The interface transition zone has always been the weak point of concrete and recycled concrete. In order to further study the influence of interface transition zone on the damage performance of recycled concrete. In this paper, the calculation formula of the thickness of the interface transition zone of recycled concrete is deduced, and the quantitative calculation formula of the thickness of the interface transition zone of recycled concrete is obtained, and the thickness of the interface transition zone of different particle sizes of recycled concrete with the recycled aggregate content of 30% (mass fraction) is calculated. The concrete model with the thickness of 0.05 mm interface transition zone of ordinary concrete and 1 mm, 2 mm, 3 mm and 4 mm interface transition zone of recycled concrete were simulated and analyzed by using finite element analysis software. The results show that the interface transition zone of different thickness has obvious influence on the damage cracking strength of recycled concrete, and the damage cracking load of recycled concrete decreases with the increase of interface transition zone thickness. The damage cracking of recycled concrete starts from the interface transition zone, and the damage degree increases with the increase of the thickness of the interface transition zone. Compared with ordinary concrete, when the thickness of the interface transition zone is less than 2 mm (the replacement rate of recycled aggregate is less than 30%), the damage cracking load of recycled concrete does not decrease obviously.
