摘要： C30 coral aggregate concrete with chlorella control effect was prepared by adding nano-TiO2 and hydrophobic material, and the effects of nano-TiO2 and hydrophobic material on the basic properties of C30 coral aggregate concrete and chlorella control effect under different experimental conditions were compared. The experimental results show that nano-TiO2 and hydrophobic materials have a certain degree of influence on the basic properties of concrete, but the influence is not significant. Under long-term immersion, nano-TiO2 and hydrophobic materials can inhibit the growth of Chlorella vulgaris. The maximum fluorescence value of concrete is decreased by 53.6% after adding TiO2, and the maximum fluorescence value of concrete is prolonged by 20% (1 day). The maximum fluorescence value of concrete is decreased by 67.7% after adding hydrophobic materials, and the maximum fluorescence value of concrete is also prolonged by 20% (1 day); Under the condition of simulated tidal water, the inhibition effect of Nano-TiO2 on the growth degree and growth rate of Chlorella vulgaris is weakened, at this time the maximum fluorescence value of concrete mixed with nano-TiO2 is decreased by 50.5%, and the maximum fluorescence value is only prolonged by 14.3%; while the inhibition of hydrophobic materials on the growth degree and growth rate of Chlorella vulgaris is enhanced significantly, and the maximum fluorescence value of concrete with hydrophobic materials is decreased by 80.3%; the maximum fluorescence time is prolonged by 114.3%.
