【摘要】 主要分析了混凝土耐久性和几种掺合料对混凝土耐久性的影响,并进行了一系列的试验研究,其中包括混凝土抗氯离子渗透能力、抗渗性能、抗冻融性能、抗碳化性能、抗碱-集料反应能力等.试验结果表明,掺合料的加入能使混凝土结构变得更为密实,从而明显改善混凝土的耐久性.更多还原

【Abstract】 The durability of concrete and the influence of several admixtures on the durability are mainly analysed. A series of experiments were done, including experiments of chloride ion permeability resistance, performance of permeability resistance, freeze-thaw resistance, carbonization resistance and alkali-aggregate reaction resistance of concrete. The experimental result shows that the mineral admixture can make the concrete structure denser, and then the durability of concrete is obviously improved.更多还原
