COMPRESSION STRENGTH ESTIMATION METHOD OF CONCRETE
PROBLEM TO BE SOLVED: To provide a simple method for estimating compression strength of fresh concrete capable of estimating compression strength at the site.SOLUTION: Fresh concrete FC is filled in a container 100 having heat resistance and cured for a prescribed time at a high temperature state while being radiated by a microwave M by using microwave radiation means from outside of the container 100. A penetration resistance value is measured by using a penetration resistance tester 150 with a penetration resistance test body TP in which the fresh concrete FC is semi-cured and compression strength of the penetration resistance test body TP is estimated using the penetration resistance value.SELECTED DRAWING: Figure 1
