METHOD FOR ESTIMATING STRENGTH OF STRUCTURE CONCRETE COMPRISING HIGH STRENGTH CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide a method for estimating strength of structure concrete from a structure strength correction value by estimating the structure strength correction value used for strength control of the structure concrete using high strength concrete having the design standard strength of 60 N/mmor more without performing trial mixing every ready-mixed concrete plant.SOLUTION: A method for estimating strength of structure concrete comprising high strength concrete having the design standard strength of 60 N/mmor more from compression strength of a standard curing sample created simultaneously with concrete placing is provided. The method for estimating the strength of the structure concrete is characterized by performing correction using a structure strength correction value mSn calculated, based on (I) a weight ratio (B/W) of cement (B) and water (W) when a bonding material (admixture material) is not contained, (II) a maximum temperature, and (III) a temperature rise amount (difference between a maximum temperature and a kneading temperature), on the basis of the compression strength of the standard curing sample.SELECTED DRAWING: Figure 6
