When you crush it, the result should be equal or more than 60 Mpa.

Steps for Concrete Damage Repair in Reinforced Concrete ... In case the damaged concrete effect the safety and serviceability of the structure, or the damage progress at a quick rate, then the repair process should start at once. However, if concrete damage progresses at a slow rate and not severe (detected at early stages), then many alternatives can be used to slow damage progression.
