Title:
METHOD OF DETERMINING ADDITIVE AMOUNT OF CURE ENHANCING MATERIAL AND METHOD OF PRODUCING HYDRAULIC CURED BODY
Document Type and Number:
Japanese Patent JP2020116743
Kind Code:
A
Abstract:
To provide a method of determining an additive amount of a cure enhancing material capable of attaining target strength and a method of producing a hydraulic cured body such as concrete or mortar capable of attaining the target strength.SOLUTION: A method of determining an additive amount of a cure enhancing material determines the additive amount that attains strength satisfying target strength as an appropriate additive amount of the cure enhancing material based on the strength obtained from the following steps (A) to (C). The strength measurement steps of a sample includes: (A) a measurement step, with respect to a temperature history of a real material, of measuring the temperature history of the real material; (B) a heat curing step, with respect to the sample, of placing the sample including the cure enhancing material with additive amounts of plural levels to stay in a constant temperature and humidity tank that is programmed with the temperature history and performing heat curing according to the temperature history; and (C) a strength measurement step, with respect to the sample, of measuring the strength of the sample subjected to the heat curing.SELECTED DRAWING: Figure 2
