摘要
采用氧扩散法测定了砂浆试件的渗透性。在快速试验条件下研究了波特兰水泥一粉煤灰砂浆的抗硫酸盐性能，探讨了水泥和粉煤灰的类别、细度和胶凝材料组成以及水次比和养护条件等对硫酸盐侵蚀环境下砂浆力学性能的影响规律和影响机理。
The sulfate resistance of cement -- fly ash mortar in accelerated test adopting higher sulfate concentration was researched by measuring the permeability of mortar specimens with an oxygen diffusion equipment. The effect rule and mechanism of some factors, such as kind of cement or fly ash, specific surface area, composition of cementitious material, ratio of water to cementitious materials and curing conditions, on the mechanical properties of mortar of concrete subjected sulfate attack was studied in this paper.
