Abstract: Concrete is seriously corroded by organisms in the marine environment, among which diatom is an important organism in the ocean, which plays the role of primary producer in the ecosystem, and occupies a considerable proportion in the Marine environment. In thiswork, the growth characteristics of diatom and its adhesion evolution on concrete surface were studied. Firstly, the growth and propagation characteristics of diatom were studied, and then the influence of diatom on the performance of concrete at different growth stages was explored by measuring pH value, salinity, total dissolved solid matter and dissolved oxygen in the culture medium, combined with microscopic observation, X-ray diffraction and chloride ion permeability test. The results show that the growth of diatom reaches its peak on the 7th day and then declines gradually. Its life activities will cause the dissolved oxygen value of the culture medium to fluctuate obviously, the pH value increases first and then decreases, the total dissolved solid matter and salinity continue to rise, aggravating the corrosion of concrete. With the extension of test age, the corrosion becomes more and more serious, in which the compressive strength of concrete decreases by 8%, and the mobility of chloride ions increases by 83.3%.
