摘要
通过对国标GB/T 6155-2008和GB/T 5071-1997中的试验方法进行综合,得出一种新的真密度检测方法(简称综合法)。用综合法检测的硅砖、石油焦试样的真密度分别为2.337 0g/cm3和1.816 8g/cm3,国标方法检测的结果为2.335 0g/cm3和1.817 2g/cm3,两种方法检测的结果相差无几。经过与国标方法和其他方法的比较得出:综合法更加方便快捷、安全准确,既适合炭素材料,也适合其他材料如耐火材料的真密度检测。
Synthesized the experimental methods in the national standard GB/T 6155-2008 and GB/T 5071-1997,then a new way for the testing method of true density was gotten（synthesized method for short）.The respective true density which were gotten by synthesized method of silica brick and petroleum coke were 2.337 0 g/cm3 and 1.816 8 g/cm3,when the results got by national standard were 2.335 0 g/cm3 and 1.817 2 g/cm3,and there were little different between the results of two methods.The conclusion compared two methods was that： synthesized method was more quick,safe and exact at the same time,and it can be used in carbon material and other material such as refractory and so on.
