离心法测试砂子吸水率的研究

ON THE METHOD OF MEASURING THE RATIO OF WATER ABSORPTION OF SANDS WITH CENTRIFUGAL MACHINE

研究了离心机为脱水手段测试砂子吸水率的方法，从活性剂的选择，脱水样筒的设计、测试规程的制定等方面介绍了这一方法的具体内容，并通过一定数量的实测结果验证了这一方法的有效性和优越性。

The method of measuring the ratio of water absorption of sands with a centrifugal machine is studied.The concrete contents of the method are discussed from the anyles of selection of activatos,design of the dehydrating container and formation of measuring rules.Effectiveness and superiority of the method are proved by measuring some practicall results.
