摘要
结合杭州湾大桥的工程实际,通过对复合胶凝材料作用机理的探讨,采用复合配伍技术,对水泥+矿粉(粉煤灰)二元复合胶凝材料对海工耐久混凝土的和易性、力学性能及抗氯离子渗透等性能的影响进行了试验研究,提出了技术可靠、经济合理的配伍方案,并以此为基础,采用大掺量复合矿物外加剂掺入,配制出符合工程设计技术要求和经济合理的海工耐久混凝土。
The binary compound cementitious materials, cement and mineral filler or fly ash were studied in this paper to investigate the compatibility, strength and resistance to chloride ion of durability concrete for maritime works. The test results indicated that a kind of reasonable and economic durability can be obtained by the high dosage of mineral admixtures.
