ADMIXTURES. Admixtures are the other primary ingredient of modern concrete and the most important is air-entraining admixture. Any concrete that will be exposed to freeze-thaw and deicing salts must have entrained air to prevent spalling of the surface and even complete breakdown of the concrete. In severe exposure areas, the air content should vary from 7.5% for 3/8 inch maximum sized ...
