Abstract
In order to investigate the compressive property of the concrete corroded by seawater in low-temperature, compressive tests are conducted on concrete specimen, which are corroded by accelerated corrosion method. Artificial seawater solution (Major ions concentration are five times of yellow seawater), are applied as the corrosive medium in the laboratory. Uniaxial compressive mechanical properties of the concrete tests, including 60 prism concrete specimens, are carried out. The physical and mechanical properties (including surface, mass, compressive strength, elastic modulus et al) of concrete in the different corrosion degree are researched. Taking the strength degradation ratio and elastic modulus loss as damage index, effects of the corrosion solution on the property of corroded concrete are discussed in detail. Relationships between the damage index and corrosion state of specimens are achieved.
