摘　　要：研究了胶凝材料用量、砂率、矿物掺合料和引气剂对高性能轻集料混凝土抗氯离子渗透性能的影响规律,探讨了轻集料混凝土的抗氯离子渗透性与材料组成、密实度及孔隙特征的关系,通过调整混凝土中胶凝材料用量、水胶比、高效减水剂和矿物掺合料配比,可以有效地细化混凝土孔隙结构、改善界面区、减少不利晶相数量和提高混凝土的密实度,从而提高混凝土抵抗氯离子侵蚀的能力.Study on the effects of gelatinization material dosage, sand ratio, mineral admixtures and air- entertaining agent on the resistance of chloride ion penetration of high performance lightweight aggregate. Discuss the relationship of composition, compactness, pore characteristics and the resistance of chloride ion penetration. Through the adjustment of gelatinization material dosage, water-binder ratio, the ratio of high efficiency water reducing agent and mineral admixtures, pore structure in concrete can be refined effectively, interracial area can be improved, the number of the bad crystal phase reduced and compactness increased, which improved the resistance ability of chloride ion corrosion.
