粗砂岩高温后干密度的研究

Study on Dry Density of Grit Stone After High Temperature

对不同温度粗砂岩的干密度进行了研究,分析了粗砂岩的干密度经历了不同温度后的变化规律。结果表明:经历了高温后粗砂岩的干密度变化很小,没有明显规律性,在很多情况下可忽略不计。

Experimental study was performed on dry density of grit stone under different temperatures. The variable laws of dry density under different temperatures were analyzed. that the dry density of grit stone had small change after high temperatures which had it could be neglected in many conditions. The results showed no obvious law, and
