Measuring Method of Unit Water Content by Measurement of Air in Fresh Concrete

摘要

The present invention relates to a unit quantity measuring method of the green concrete using a unit amount of air measured by the air meter that indirectly measures the unit quantity of the green concrete by measuring the unit-air quantity of the green concrete using air meter (airmeter), Based on this will be. The step of measuring the air volume meter (V ₀₎ and the air mass meter balls (M ₀₎ of the invention only of the container (S01); Step using an air meter for measuring the actual amount of air (Air ₁₎ of the green concrete (S02); Calculating the mass (M ₁₎ of the green concrete sample contained only the air meter (S03); The volume of cement amount unit of the green concrete used in the production of raw concrete (C), the initial amount of air (Air _0), and obtaining by calculating the unit volume mass (VM ₀₎ of the green concrete is based on the blending ratio data (S04); Obtaining by calculating the actual volume of unit mass (VM ₁₎ of the green concrete (S05); And production using the raw concrete of theories unit volume (W ₀₎ and the actual unit volume mass of raw concrete unit volume mass (VM ₀₎ and raw concrete, based on the mixing ratio data (VM ₁₎ measuring the production of concrete final the unit water amount measuring method for the production of concrete comprising the step (S06) to obtain the unit of measurement of the green concrete quantity (W) is provided. ;
