Abstract Two types of sea sand concretes were prepared with sulphate aluminum cement (SAC) and ordinary Portland cement (OPC), respectively. Herein, T.t bacteria (thiobacillus thiooxidans) was used to simulate biological sulfuric acid corrosive media with different pH values (1.0, 1.5 and 2.0). Then, the effect of cement type on the degradation of sea sand concretes in simulated biological sulfuric acid corrosive media was characterized in terms of mass loss rate, compressive strength, pH value of corroded layer, fraction of solidified chlorides and pore. The results show that the hydration products of sea sand concrete with OPC or SAC were partially decomposed during the biological sulfuric acid corrosion, and the main corrosion product was CaSO4·2H2O. In biological sulfuric acid corrosive environments, the sea sand concrete with SAC presents better performance than that with OPC in terms of mass loss rate, strength deterioration, solidified fraction of chlorides and pore structure.
