摘要： 为了解决海洋环境中大体积水利工程混凝土的抗侵蚀能力和现场配制海工混凝土的质量控制问题,提出了直接使用海工水泥来简化现场混凝土拌制,并通过工程的施工实例以室内试验和现场检测数据进行分析,研究了海工水泥混凝土的耐久性能。结果表明:海工水泥混凝土拌制简单、具有很高的抗氯离子渗透能力,能满足海洋环境水利工程混凝土结构的耐久性、强度及其他工作性能要求。实例数据与分析对进一步开展相关研究和海工水泥的应用具有重要的参考价值。

Abstract: To improve the durability of mass concrete in hydraulic engineering and control the quality of field-mixed marine concrete, marine cement was directly used to simplify the in-situ mixing. The durability of marine cement-based concrete was investigated by field reconnaissance, sample inspection, laboratory test, and data analysis of existing hydraulic concrete structures. The results show that the method of mixing marine cement-based concrete is simple, and the concrete has good performance of resisting chloride penetration, which meets the requirements of durability, strength, and other working performances for hydraulic structure in marine environment. The example data and analysis in this paper could be a reference for related researches and applications.

Key words: coastal environment, durability of concrete, marine cement, case study
