Penetration of chlorides in relation to the microcracking state into reinforced ordinary and high strength concrete
Abstract Three types of concrete with compressive strengths of about 45, 80 and 100 MPa are exposed in a loaded state in a closed container and subjected to a sequence of wetting by salt fog and drying. For each concrete, the measurements of chloride content on three prismatic specimens allow us: 1/ to study the profiles of chloride ingress into concrete, 2/ to compare the different results obtained in relation to the loading state of each specimen, and 3/ to calculate the apparent diffusion coefficient $ D_{a} $. The results show the influence of concrete strength and the effect of the load applied on the penetration of chlorides into concrete. A linear relationship is found between the chloride’s apparent diffusion coefficient $ D_{a} $ and the concrete strength. There is also a relationship between $ D_{a} $ and the loading level. These relationships are established independently of the exposure period.
