Concrete compressive strength of flexural structures by destructive and nondestructive methods

Abstract

The compressive strength of concrete can be determined in a number of ways, including by using a concrete test hammer, compressing and sampling concrete samples, drilling samples at the construction site, ultrasonic testing, and more. Each method has unique benefits and drawbacks. These methods need to be investigated and evaluated, including how to conduct experiments, usage standards, measuring results, etc., as practical use has shown a wide range of benefits and drawbacks. By comparing the compressive strength of this reinforced concrete structure using destructive and non-destructive methods, the authors of this study conducted experiments on reinforced concrete floors and beams. The results demonstrate that the compressive strength is more accurately calculated when the suggested destructive method is used.

Keywords: Destructive method; non-destructive method; compressive strength; concrete test hammer; ultrasonic testing.
