| Abstract | This Tech Brief focuses on enhancing the fresh and/or hardened properties of paving grade concrete through the use of chemical admixtures. The chemical admixtures most commonly used in paving concrete are discussed in detail, specifically those used to entrain air, reduce water, and modify set. Other admixtures that are occasionally used in paving concrete are also introduced, including those for hydration control, shrinkage reduction, inhibition of the alkali-silica reaction (ASR), and for coloration. |
