生态多孔混凝土的抗硫酸盐腐蚀性能是当前的焦点研究问题。基于生态多孔混凝土加速硫酸盐干湿循环及硫酸盐浸泡腐蚀试验方法下开展生态多孔混凝土的耐久性能研究。研究结果表明:生态多孔混凝土经加速硫酸盐干湿循环腐蚀较饱和硫酸盐浸泡腐蚀其性能损失更为显著;掺加矿物掺合料对改善生态多孔混凝土的抗硫酸盐腐蚀性能并不明显。开展生态多孔混凝土抗硫酸盐腐蚀性能研究,对构建生态多孔混凝土耐久性能评价体系有着指导意义。
Sulfate corrosion resistance of ecological porous concrete is the current focus of research. Study on Durability of Ecosystem Porous Concrete Based on Accelerated Sulfate Drying and Wet Circulation and Sulfate Immersion Corrosion Test with Ecological Porous Concrete. The results show that the performance loss of the ecological porous concrete after accelerated sulfate wet-dry cyclic corrosion is more significant than that of saturated sulfate immersion corrosion; and the mixed mineral admixture is not obvious to improve the sulfate corrosion resistance of the ecological porous concrete. Carrying out research on the sulfate resistance of ecological porous concrete is of guiding significance in building the evaluation system of the durability of ecological porous concrete.
