摘要
研究了长江上游三叠系碳酸盐的碱活性 ,将小混凝土柱快速法(即超快快速法)试验结果与传统的岩相法、岩石体柱法、混凝土棱柱体法试验结果进行比较分析后认为 ,超快快速法与传统方法的结果具有较好的可比性和可靠性。结合岩相分析 ,可以利用超快小混凝土柱法作为碱碳酸盐反应活性鉴定的集料筛选方法。
The alkali-carbonate reactivily of limestons,which samples are taken fromSichuan province of China and are of Triassic Age was concurrently tested by using of every methods,including petrographic examination(ASTMC295),rock cylinder method(ASTMC586),concrete prism method(CSA A23.3-14A)and concrete microbar methed(RILEMAAR-5).Based on analysis of rezults,it is considered that the concrete microbar method(RILEMAAR-5)may be more suitable to be used for evaluating the alkali-carbonate reactivity of carbonate aggreˉgates.
