Chemical admixtures, which are primarily water-soluble substances, are discussed in detail and, in this report, are classified into 13 groups: air-entraining; accelerating; water-reducing and set-retarding; admixtures for flowing concrete; admixtures for self-consolidating concrete; cold weather admixture systems; admixtures for very high-early-strength concrete; extended set control; shrinkage-reducing; corrosion-inhibiting; lithium; permeability-reducing; and miscellaneous. Chemical admixtures are used on a daily basis in the cast-in-place and precast concrete industries. Twelve categories of admixtures are described in detail as to type, current usage, and their effect on concrete in the plastic and hardened state. Their benefits and common usage are outlined.
