本文探讨了添加复合掺合料、中砂、碎石、硅酸盐水泥、抗硫水泥搅拌而成的高性能混凝土,在含有硫酸根离子的溶液中经过一百次干湿循环,通过重量的变化率、抗折强度与抗压强度发生的变化来分析硫酸盐对混凝土耐久性产生的影响。结果显示重量变化率对混凝土能体现出耐久性能;抗折强度与抗压强度比起来前者比较敏感,对于硫酸盐给混凝土造成的破坏能够较好的显现,通过本文的探讨,期望对以后的混凝土施工能够带来好的影响。
This paper discusses the addition of composite admixture, sand, gravel, Portland cement, anti-sulfur cement mixing high performance concrete, containing sulfate ions in the solution through a hundred times wet and dry cycle, by weight Rate of change, flexural strength and compressive strength changes to analyze the impact of sulfate on the durability of concrete. The results show that the rate of change of weight can reflect the durability of concrete. The flexural strength and compressive strength are more sensitive than the former, which can well show the damage caused by sulphate to concrete. Through the discussion of this paper, Construction can bring good effects.
