Testing Concrete Cores - Civil Engineering
Concrete in the member represented by a core test shall be considered acceptable, if the average equivalent cube strength of the cores is equal to at least 85 percent of the cube strength of the grade of concrete specified for the corresponding age and no individual core has a strength less than 75 percent. In case the core test results do not satisfy these requirements, or where such tests ...
