摘要
骨料中所含活性组分的粒径及其含量对骨料ASR膨胀的影响一直是工程界所关注的重点之一。本文对具有不同粒径及不同含量活性组分的骨料进行的ASR膨胀试验结果表明,试件的最大ASR膨胀并不与骨料中活性组分量的类型及数量直接相关,骨料存在着引起试件最大膨胀的特定含量及特定粒径。
Effects of the grain sizes and content of the active components in the aggregates are one of the focal points that the engineering consistently pays attention to. In this paper ASR expansion tests are conducted for the aggregates containing different grain sizes and contents of the active components. The test results indicate that the largest ASR expansion of the specimen does not directly related with the amounts and types of the active components contained in the aggregates, and there are specific tents and grain sizes of the active components contained in the aggregates that cause the largest expansion of the specimen.
