耐火浇注料单位体积用量与体积密度的差异

Difference between castable amount per unit volume and bulk density

指出了耐火浇注料单位体积用量与体积密度定义上的区别，并且介绍了一种测试耐火浇注料单位体积用量的试验方法。通过试验结果直观地揭示了耐火浇注料的单位体积用量与其体积密度之间存在的差异，以及不同种类的浇注料两者差异程度的不同。以水硬性耐火浇注料为例分析了造成这一差异的原因。

The difference between castable amount per unit volume and bulk density in definition has been pointed out and amethod to test castahle amount per unit volume has been introduced. It is directly perceived through the test resultsthat a difference exists between castable amount per unit volume and bulk density. This difference differs to some extent in different castables. The reason that this difference was brought about has been analyzed by taking hydraulicsetting castahle as an example.
