摘要

摘要: 采用ASTM C1202的方法对混凝土抗氯离子渗透性能进行研究,结果表明,混凝土抗氯离子的渗透能力随水灰比的降低而提高,但水灰比的降低不能有效地提高混凝土的抗渗性能;粉煤灰、硅灰的掺入能有效提高混凝土抗氯离子渗透能力,且在一定范围内随粉煤灰掺量的增加,混凝土的抗渗性能提高;粉煤灰与硅灰复合配制的混凝土抗氯离子渗透的能力较好,粉煤灰与硅灰双掺是配制高抗氯离子渗透混凝土的有效途径之一。

Abstract: The high performance concrete's impermeability to chloride ions is studied using the method in ASTM C1202.The result shows that the decrease of W/C ratio can reduce the penetration of chloride ions into the concrete,but the impermeability of the concrete can not be improved effectively by decreasing W/C ratio.When fly ash and silica fume are added into the concrete,penetration of chloride ions is on the decline.The resistance to penetration of chloride ions into the concrete can be further improved by combining silica fume with fly ash added into the concrete,and concrete combining silica fume with fly ash is one of the effective methods to get HPC with high impermeability to chloride ions.
