METHOD OF MEASURING NON-DESTRUCTIVE STRENGTH OF CONCRETE USING SOUND SIGNAL ENERGY

摘要

The present invention relates to a method of measuring non-destructive strength of concrete using sound signal energy. To measure a strength of concrete, a sound signal generated when concrete is hit is measured, and non-destructive strength of concrete is measured using sound signal energy which is a size thereof. As such, various problems such as burden and inconvenience caused during preparation of test piece specimen and destruction test steps of a direct strength measuring scheme, time delay, and damage to a structure caused by sample extraction on a site are able to be reduced. Moreover, estimation of strength restrictions with respect to various types of concrete during an indirect strength measuring scheme and a problem in which strength is difficult to accurately be estimated are able to be reduced. Reliability and site application with respect to concrete strength are simultaneously improved; thereby economic feasibility and stability are able to be enhanced with respect to design, construction, and maintenance of social infrastructures including civil engineering and construction structures.;COPYRIGHT KIPO 2017
