Abstract

Abstract

In order to study the change law of bonding performance between ordinary deformed steel bar and ceramic concrete under the combined action of continuous load and chloride corrosion. The study analyzed the influence of three factors of ceramic concrete strength, salt solution concentration and load holding level through pull-out test, a total of 66 pull-out specimens, and putted forward the calculation formula of ultimate bond strength under the combined action of continuous load and chloride corrosion. It was found that the specimen under the combined action of continuous load and chloride erosion had splitting failure, which was the same as the control specimen, but the debris produced after splitting increased. The effect of load holding level on the ultimate bond strength was different. When the salt solution concentration was 5%~15%, the ultimate bond strength of the specimen with 20% load holding level was higher than that of the specimen without load holding, but when the load holding level was 40%, the ultimate bond strength of the specimen was lower. The fitting result of the proposed calculation formula of ultimate bond strength was good.
