Research on Corrosion Effect of Sulfate Ions on Concrete Under Wetting-Drying Cycle
文献摘要：
Saline soil is widely distributed in the marine sediments along the coast of the world and the arid-semi-arid areas of the Middle East and Iraq, and calcium sulfate erosion has become one of the important factors affecting the durability of concrete in this area. In order to clarify the mechanism of sulfate ion damage to concrete, this paper mainly takes saline soil with high sulfate content in coastal area as well as arid-semi-arid area as the research object, and uses indoor geotechnical test, field test and numerical simulation to study the influence of different dry-wet cycle times on the unconfined compressive strength of concrete test blocks, and puts forward the relationship between the erosion arrival depth and time of sulfate ion in concrete, so as to predict the long-term erosion depth by using the erosion depth of sulfate ion in concrete in short time. The results show that the shorter the erosion time when the erosion reaches a certain depth, and the larger the erosion reaches when the erosion time is the same, the faster the erosion reaches the depth with the increase of erosion time. Compared with rectangular section concrete, circular section concrete penetrates faster. The results of this study can provide a reference for the durability design of concrete in saline soil sites containing sulfate.
