碱-硅酸反应是碱-骨料反应中最常见的反应,检测含活性硅成分的骨料是否有潜在碱-硅酸反应的常用方法——砂浆棒快速法,而不同的标准对该方法却有不同的规定,极易造成使用时的混淆,影响检测结果。评述了国内现行的五个标准对该方法规定的异同,指出要重点关注水泥使用、试件成型、试件测试和结果处理四个方面,并结合实际,在增大试验成功率和减小误差方面给出建议。
Alkali-silicic acid reaction is the most common reaction in alkali-aggregate reaction, and the common method to detect whether there is a potential alkali-silicic acid reaction in the aggregate containing active silicon component-mortar rod fast method. Different standards apply this method However, there are different requirements that can easily lead to confusion in use and affect the test result. This paper reviews the similarities and differences between the current five standards in this method and points out that it is necessary to focus on the four aspects of cement use, specimen forming, specimen testing and result processing. In combination with reality, the success rate and the error of testing are increased Suggestions are given.
