AbstractAbout AuthorsReferences
The analysis of scientific, technical and normative literature on the use of shotcrete shows that focusing on high strength and water tightness, the authors state that the shotcrete has high corrosion resistance. The presented test results do not always confirm this position. Insufficient study of the corrosion properties of shotcrete limits the scope of its application not only for concreting new structures, but also for repair work. For the use of shotcrete as a protection of reinforced concrete structures against aggressive impacts of the environment, data on its sulfate resistance and diffusion permeability for chlorides as the most aggressive media are required. On the basis of the performed studies of shotcrete in sulfate and chloride media, the normalized parameters of shotcrete of increased corrosion resistance were determined. The data obtained make it possible to consider shotcrete as an effective protection of concrete and reinforced concrete structures against corrosion in sulfate and chloride media
