一、稠度测定的现状稠度的在线测定在我国是一项尚未解决的问题。现在沿用的稠度或工作度测定方法,是在搅拌完成后取样,大多数用坍落度筒测定;其它形形色色的测定方法,仍均需在搅拌完成后取样测定。靠这些测定方法已无法纠正拌和物的稠度或工作度的偏差,因此渴望有一种能在拌搅过程中就测知稠度或工作度的方法及仪器,以便随时控制混凝土的质量。国外已有利用搅拌时的功率过程曲线控制拌和物稠度的专利,宣称可以用来代替水的计量设备。国外混凝土杂志上还可 I. On-line determination of the consistency of the consistency measurement is an unsolved problem in our country. The method of consistency or workability that is used now is sampling after the completion of the stirring, most of which is measured with a slump cylinder; other methods of measuring various colors are still required to be sampled after the completion of the stirring. With these measurement methods, it has been impossible to correct the deviation of the consistency or workability of the mixture. Therefore, there is a desire for a method and apparatus capable of measuring the consistency or workability in the mixing process so as to control the quality of the concrete at any time. In foreign countries, patents have been used to control the consistency of blends by using the power process curve during mixing, claiming that they can be used instead of water metering equipment. Foreign concrete magazines can also be
