What is air-entrained concrete?
Air-entrained concrete contains billions of microscopic air bubbles that enable the concrete to resist the damaging effects of freezing and thawing. This is achieved by the addition of an air-entraining admixture at the ready-mixed plant. Air-entrained concrete should be used whenever concrete will experience freezing so is essential for driveways, patios, footpaths and roads in cold or temperate climates. Air-entrainment cannot be achieved when mixing concrete by hand.
