Compressive Strength Test on Concrete Core
Compressive Strength Test on Concrete Core

Compressive strength of concrete is the resistance provided by concrete when a compressive load is applied to it. Concrete has very high compressive strength. Most of the design of concrete structures is done by adopting the value of its compressive strength.

Table 1.1 Example Core Tests Results Notice that a series of coring samples are obtained as per table 1.1. According to ACI 318, as stated in ACI 214-4R-03 Chapter 7, the suspected concrete is considered adequate if the average corrected strength of the three cores exceeds 0.85fc’ and no individual strength is lesser than 0.75fc’. ’. Therefore to calculate the compressive strength fc ...
