Title:
METHOD AND APPARATUS FOR MANUFACTURING CONCRETE
Document Type and Number:
Japanese Patent JP3525099
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing a concrete for enhancing reliability of an admixture slurry in manufacture of the concrete by facilitating a concentration management without necessity of excessively prolonging a kneading time.
SOLUTION: The method for manufacturing the concrete comprises the steps of continuously measuring a concentration of the admixture slurry, calculating and regulating an amount of the admixture slurry to be mixed according to a measured concentration of the slurry and a target value of an admixture fine powder blended in the concrete. The apparatus for manufacturing the concrete comprises an admixture slurry storage tank having return piping for returning the overflowed slurry to an admixture slurry regulating storage tank for temporarily storing a predetermined amount of the slurry on the way of a supply passage from the regulating storage tank to a metering tank, and a concentration measuring unit for measuring the concentration of the slurry between the slurry storage tank and the regulating storage tank.
