摘要
本文对超声脉冲法运用于高强、超高强砼的非破损检测、作了探索性研究。此方法不仅适用于砼强度值为20~120MPa的工程检测,而声速—含水率综合法测强技术又使超声脉冲测试精度提高到一个新台阶。
Ultrasonic pulse methods for nondestructive testing of the highstrength concrete and uitra--high--strength concreteare explored.These methods are not only suitable for examination of the concrete whose strength value is 20~120MPa, but one of them,i. e. acoustic velocity--water content combination method,also increase the precision of ultrason-ic pulse testing to a new stage.
