Experimental Study on Permeability and Chloride Resistance Properties of Concrete in Yu-Cheng Bridge

Abstract:

This paper studies air permeability, water absorption and chloride resistance properties of the normal concrete (NC) and the high performance concrete (HPC) adopted in the Yu-Cheng Bridge, Zhejiang Province. The air permeability and water absorption were measured by Autoclam, while the chloride resistance were tested by RCT after accelerate chloride ingression in the salt spray cabinet. The relationship among the air permeability, the water absorption and the chloride resistance of both kinds of concrete were analyzed. According to the result of Autoclam, HPC shows better resistance abilities of air permeability and water absorption, and this indicates that HPC is denser than NC. RCT shows that the chloride resistance of HPC is better than that of normal concrete.
