Background

The detection methods for detecting the strength of the concrete on site are various, such as a core drilling method, a pulling-out method, an indentation method, a shooting method, a rebound method, an ultrasonic method, a rebound ultrasonic comprehensive method, an ultrasonic attenuation comprehensive method, a ray method and the like, wherein the rebound method and the ultrasonic rebound comprehensive method are the most widely applied nondestructive detection methods.

The relationship curve established between the compressive strength of the concrete test block and the parameters (ultrasonic sound velocity value, rebound value, extraction force and the like) of the nondestructive testing is called as a strength measurement curve, and is the basis for estimating the concrete strength by the nondestructive testing. The strength measuring curve is divided into a unified strength measuring curve, a regional strength measuring curve and a special (rating) strength measuring curve according to the material source.

The method for detecting the compressive strength of a common concrete structural member by using a resiliometer (a direct-injection hammering type instrument) is called a rebound method for short. The rebound method is a method of estimating the strength of concrete by using a spring-driven weight to bounce the surface of concrete through a bounce lever (dowel lever), measuring the distance of the rebound of the weight, and using the rebound value (the ratio of the rebound distance to the initial length of the spring) as an index related to the strength. The measurement is carried out on the surface of the concrete, so the method belongs to a surface hardness method, and is a detection method established on the basis of the correlation between the surface hardness and the strength of the concrete.

The resilience method for detecting the concrete strength has the characteristics of simple equipment, convenience in operation, rapidness in test and the like, does not damage the concrete structure, and has greater advantages than other detection methods.
