摘要
结合多年的工程实践 ,对测定骨料碱活性的试验方法如岩相法、化学法、砂浆长度法、快速法和砼棱柱体法进行了评述。认为 :对骨料的碱活性决不能仅依靠一种方法来作出判断 。
The test methods at home and abroad for determining alkali aggrgate reaction(AAR) are divided as follows:the lithologic test method,the chemical test method,the mortar bar length test method,the quick mortar bar test method,the rock cylinder method and the concrete prismatic test method.The above different test methods are discussed in connection with long term egineering experience.The evaluation of AAR is suggested to be determined by various test methods insteady of single one.
