PROBLEM TO BE SOLVED: To provide a method for inferring a unit water amount of a ready mixed concrete capable of accurately inferring the unit water amount of the concrete by inferring a variation of a water content of a mortar before or after wet screening. SOLUTION: The method for inferring the unit water amount of the ready mixed concrete comprises the steps of extracting the mortar 20 by wet screening the ready mixed concrete 1, correcting a variation of an air amount or the like of the concrete according to a relational equation of a unit mass of the extracted mortar 20 after wet screening, water content, proportion of the concrete, characteristic value of used aggregate, the air amount of the concrete and the like as variations, and obtaining the unit water amount of the concrete 1. |
