Analysing Indirect Methods for Comparatively Determining the Compressive Strength of Materials with Various Properties

Abstract

The properties and compressive strength of hardened concrete are examined by destructive and non-destructive testing methods. There was no direct relationship between non-destructive testing results for existing concrete structures. This article describes the comparison between rebound and compression hammer tests of hardened concrete. It also describes the comparison of strength and cube compressive strength as well as the comparison of modulus of elasticity according to different standards.Destructive and non-destructive techniques were used in an experimental programme on various concrete mixtures, including M20, M25, and M30. A comprehensive technique was used for evaluating the compressive strength properties of concrete grades M20, M25, and M30, using both destructive and non-destructive testing methods. The impact strength, maximum load, Schmidt hammer, and uniaxial compression test findings have been also reviewed within the examination. The study’s primary purpose was to clarify the connections between specific evaluations technique and actual grades. Similarly, those connections were subjected to an in-depth validation technique using previously advanced formulation from previous research, which produced precious statistics about the assessment of concrete strength. These findings increase our understanding of concrete’s behaviour and provide essential path for destiny packages inside the engineering and construction industries, enabling properly-informed decision-making in those domains.
