摘要
以我国西部强腐蚀软地基条件下新疆与西北主网联网750kV第二通道输变电工程为背景,通过对工程地区地下水水化学分析,在预先设计的几种混凝土备选配方的基础上进行了抗硫酸盐侵蚀试验和复盐溶液侵蚀试验、抗氯离子渗透性能试验及不同养护环境下混凝土的抗压强度试验,并以水泥化学成分和掺合料掺量为主要区分因素,最终优选设计出了适用于该类腐蚀环境下的混凝土配方,为强腐蚀及高寒环境下混凝土耐久性研究提供了参考。
The research background is the pile foundation concrete formula design of electric transmission line in western of China, where the foundation of construction site is high-corrosion circumstance. The target of this paper is to propose a concrete formula which can resist the compound attack of sulfate and chloride. Firstly, compound solution was made up to simulate the groundwater corrosion circumstance. Then, the following tests were carried out： sulfate solution attack test, groundwater attack test, chloride ion permeability test and compressive strength test under different curing environment. Chemical composition of cement and admixture quantity are considered as distinguish factors, an adaptive formula was finally obtained by series of optimization. According to the test results, the formula is proved effective in re- sisting compound corrosion. The scheme and results in this paper can he extended to similar studies on corrosion-resistant concrete.
