Pigments change the color of the concrete for aesthetic reasons.Alternatively, Plasticizers and Superplasticizers can be used to lower the water content in the concrete while keeping a decent level of workability. They are particularly helpful when placing concrete around congested rebar arrangements. Plasticizers and Superplasticizers improve the workability of the concrete during the wet (or plastic) stage allowing the concrete to flow more easily.These tiny air bubbles help the concrete resist the freeze-thaw cycles with much less cracking and damage. Air entraining agents add and help distribute tiny air bubbles throughout the concrete.Often used in hotter temperatures so the concrete doesn’t set too quickly, allowing the concrete finishing crew to get the proper finishing work completed. Retarders slow the hydration, or hardening, of the wet concrete. Often used in colder temperatures so the concrete crew has less waiting time between placing and finishing the concrete.
