Types of Concrete, Their Strengths & Applications

PAV 1 designated concrete are air-entrained concrete mixes. The air-entrainment process purposefully forms tiny air bubbles within the concrete, which boosts both its durability and its ability to withstand freeze-thaw cycles. The presence of bubbles also increases the workability of the concrete whilst in a plastic state.
