Rate of Strength Gain of Concrete Concrete Strength

As the porosity increases, the compressive strength of the concrete will decrease. Soundness of aggregate. If the aggregate in concrete is weak, the concrete will also be weak. Rocks with low strength, such as chalk, are clearly unsuitable for use as aggregate. Aggregate paste bond. The compactness of the bond between the paste and the aggregate is critical.
