| 摘 要： | 适量掺加矿物掺合料可以降低混凝土结构的孔隙率,提高水化产物的致密性,有效降低氯离子的渗透性,提高混凝土的使用寿命。本文主要研究了钢渣作为掺合料单掺或复掺对混凝土Cl-渗透性能及力学性能的影响,并分析探讨了其影响机理。结果表明:一定量的钢渣和粉煤灰复掺可以较好的提高混凝土抗压强度;随着钢渣掺量的增加,混凝土坍落度降低,抗氯离子渗透性能逐渐下降;钢渣与粉煤灰复掺时,混凝土抗氯离子渗透性能增加;大掺量(钢渣、粉煤灰掺量50%)掺合料可以提高混凝土抗氯离子渗透性能。

| Abstract: | The mineral admixture can reduce the pore porosity and improve the chloride ion permeability of concrete.The influence of steel slag as mineral admixture on mechanical properties and chloride ion permeability of concrete were studied,and the reaction mechanism of steel slag in concrete was discussed in this paper.The results showed that the concrete doped with steel slag and fly ash can increase the compressive strength of concrete;and with the steel slag content increased,the slump and the chloride ion per... |
