Probing of Mortar Specimens Using Ultrasonic Method Based on the Aging of Mortar
초록
Ultrasonic method is useful in determining the compressive strength of concrete as a nondestructive testing technique. As the velocity of the ultrasonic wave changes depending the aging of fresh concrete, it is possible to use the ultrasonic method to measure the degree of concrete curing on site. Recently, the use of steel reinforced concrete is ever increasing. This study is to examine the effect of aging concrete on the velocity of ultrasonic wave so that the compressive strength of concrete can be predicted in the presence of steel inclusions.
