Procedure For Concrete Sample Preparation Concrete

By keeping concrete moist, the bond between the paste and the aggregates gets stronger. Concrete doesnt harden properly if it is left to dry out. Curing is done just after finishing the concrete surface, as soon as it will not be damaged. The longer concrete is cured, the closer it will be to its best possible strength and durability.
