Spalling is a loss of the surface Portland cement that exposes the course aggregate. It is caused by freeze-thaw cycles and deicing salts. The best defense against spalling is to use an air-entrained concrete with a 3 to 5 inch slump. Once the contractor has a good concrete mix, they can compromise it by using poor construction techniques.
