为了保证大连金渤海岸高腐蚀环境下混凝土的耐久性,保证工程质量,本文采用干湿浸烘循环试验对其进行研究,并利用正交设计对实验结果进行分析,考察水灰比、矿物掺合料以及阻锈剂的掺量对钢筋锈蚀的影响,结果显示矿粉掺量是最大的影响因素,水灰比小于0.45时对钢筋锈蚀影响不大,粉煤灰的掺量可以达到胶凝材料的25%。 In order to ensure the durability of concrete under high corrosive environment in Dalian JinBo coast and ensure the project quality, this paper uses wet-dry immersion cycle test to study it and uses orthogonal design to analyze the experimental results. The effects of water-cement ratio, The results show that the content of slag is the biggest factor. When the ratio of water to cement is less than 0.45, it has little effect on the corrosion of steel, and the content of fly ash can reach the level of gelling 25% of the material.
