METHOD FOR MEASURING BASIC FLUID WATER VOLUME OF MIXTURE COMPOSED OF LIQUID, POWDER AND GRAIN AND METHOD FOR DECIDING CHARACTERISTICS OF VARIOUS KINDS OF COMPOUNDS IN SAID MIXTURE SYSTEM AND METHOD FOR PREPARING SAID MIXTURE

摘要

PURPOSE:To make rational elucidation promptly responding with the actual state of a kneaded mixture by determining the critical relative adsorptive water rate of the grain in a mixture composed of liquid, powder and grain and determining the moisture content in the capillary range of the powder. CONSTITUTION:The critical adsorptive water rate of the grain and the moisture content in the capillary range of the powder are determined in the mixture composed of the powder of cement, etc., the grain such as sand and the liquid such as water in the packed matter of the most closely packed state obtd. by subjecting the above-mentioned mixture to compacting and packing operations. The water volumes obtd. by subtracting the respective weights of the grain and powder in the closest packed matter and likewise the critical adsorptive water volumes obtd. by multiplying the above-mentioned weight of the grain by the critical adsorptive water volume and multiplying the above-mentioned weight of the powder by the above-mentioned moisture content in the capillary range respectively from the weight per unit volume of the above-mentioned packed matter in the most closely packed state are determined as the basic water volumes governing the flowability and other characteristics in the above-mentioned closest packed matter. The characteristics of the above-mentioned mixture are exactly recognized by preparing said mixture with the basic fluid water volume as an index.
