[sixty eight] As soon as the combine is exactly where it ought to be, the curing procedure has to be controlled to make certain that the concrete attains the desired characteristics. Through concrete preparing, many technological details might have an impact on the quality and nature from the product.

Air entraining brokers entrains microscopic air bubbles during the concrete: when the hardened concrete freezes, the frozen water In the concrete expands into these air bubbles instead of damaging the concrete.
Water runs throughout the voids from the pavement towards the soil underneath. Air entrainment admixtures in many cases are Employed in freeze-thaw climates to attenuate the possibility of frost injury. Pervious concrete also permits rainwater to filter by roads and parking tons, to recharge aquifers, as opposed to contributing to runoff and flooding.[ninety two]
