Hardened Concrete Core Test for Compressive Strength

Nowadays concrete core test is a famous and well-established method for the assessment of the compressive strength of the hardened concrete. Core testing enables visual inspection of the interior regions of a concrete member which is also related to strength estimation. Concrete coring also enables to evaluate other properties of the Reinforced Concrete Framed Structure by concrete core test.

Standards for 7-day and 28-day strength test results
