This paper describes the evaluation of strength development properties of concrete at early ages using maturity method, nondestructive method such as ultrasonic velocity by pundit and rebound number by P type Schmidt hammer. Strength development properties were regression analyzed, and the ultrasonic velocity measurement is useful to monitor the setting and hardening process of concrete at early ages, but it does not increase and converge on a certain value after 100˚D·D. Compressive strength during 7days has a good relationship with maturity for all of the curing methods, and strength prediction formula can be derived from the relationships between compressive strength and ultrasonic pulse velocity, rebound number, respectively. |
