碱激发胶凝材料抗酸侵蚀性的试验研究

摘要

对碱激发胶凝材料和普通硅酸盐水泥的抗酸侵蚀性进行了试验研究,对碱激发胶凝材料的耐酸机理作了分析,结果表明碱矿渣和碱粉煤灰胶凝材料具有良好的抗酸侵蚀性能,水泥和碱偏高岭土胶凝材料的抗酸侵蚀性能均较差,结论是胶凝材料的耐酸性不仅仅由反应产物的种类决定。%An experimental research on the acid resistance of alkali-activated cementing materials and ordinary cement is carried out,acid research mechanism of the alkali-activated cementing materials are also analyzed.The test results show that alkali-activated slag and fly-ash cementing materials have good acid resistance,while ordinary portland cement and alkali-activated metakaolinite have low acid resistance.It is a conclusion that the acid resistance of cementing materials are not decided by the types of the products.
