Abstract
PURPOSE: To make judgement and decision on the reuse, control, throw-away, etc., of sludge water without the needs for skilfullness by measuring the concentration, apparent specific gravity, etc., of the sludge water discharged from fresh concrete plant by means of an arithmetic unit.
CONSTITUTION: In order to make a judgement on whether or not sludge water discharged from fresh concrete plant can be reused as mixing water for fresh concrete, characteristic values, e.g., the concentration, apparent specific gravity, etc., of the sludge water are measured by using an arithmetic unit consisting a balance 10, a calculator 20, plural quantitative measuring meters 1, and standard weight 2 for the analysis of the sludge water. Then, necessary values are calculated by key operations and printed out on a printer 29. From these characteristic values so calculated, the adequacy of the sludge water to be reused for the manufacture of fresh concrete or should be discarded can be decided simply and rapidly.
