| 摘 要： | 通过正交试验设计,初步确定锂渣复合粉煤灰高性能混凝土的配合比,然后从中选出几组配合比通过RCM法测定了锂渣复合粉煤灰高性能混凝土氯离子扩散系数,分析了添加锂渣和粉煤灰的高性能混凝土和不添加这两种掺合料混凝土的抗氯离子性能不同的原因,结果表明:添加锂渣和粉煤灰的混凝土的抗氯离子渗透性能明显高于不添加这两种掺合料的混凝土的抗氯离子渗透性能。

| Abstract: | Identifies the mixture ratios of the lithium slag composite fly ash of high performance concrete(HPC) through orthogonal experiment design were initiall,and then chooses a few groups from them to determine the chloride diffusion coefficient of the lithium slag composite fly ash of the HPC through RCM method.Next it analyzes the reasons why the anti-chloride ion performance of the HPC is different between the adding lithium slag and fly ash and not adding the two mixtures concrete.The results show that the anti-chloride ion permeability of adding lithium slag and fly ash concrete obviously higher than not adding that two kinds of mixture of concrete. |
