Non-Destructive Testing Technology of Compressive Strength of Concrete Targets
According to rebound-ultrasound procedures combined method of concrete strength, a reboundultrasonic integrated model of strength curve was established by using on-site concrete targets rebound value and ultrasonic velocity data. Numerical software was written to make comparative experiment to curve model with field experimental data and to obtain more reliable strength results of concrete targets. Error of less than 10% was obtained, proving the feasibility of measuring concrete targets with rebound ultrasonic.
