摘要
南水北调工程单项工程多,工程结构复杂,因此对混凝土耐久性要求较高,如何提高混凝土的耐久性显得尤为重要。在实际工程施工中,根据环境特点和原材料的性质,采取提高混凝土抗渗性、抗冻性,防止钢筋锈蚀,抑制碱骨料反应,控制硬化混凝土体积的稳定性等措施提高混凝土耐久性,为提高南水北调工程混凝土的耐久性提供了重要依据。
Featuring in much single projects with complicated structures, the South-to-North Water Transfer Project has higher requirements for concrete durability. How to improve concrete durability is of great importance to the project. The article proposes some measures to boost concrete durability as raising concrete impermeability and frost resistance, protecting steel bar from corrosion, restraining alkali aggregate reaction and controlling stability of concrete hardening.
