Sika® Plastiment® R 168 is a ready to use, liquid admixture for producing more uniform and predictable quality concrete. It reduces the quantity of mixing water to produce concrete of a given consistency, with greater economy, for a given strength. The use of Sika® Plastiment® R 168 with concrete increases cohesion and reduces segregation. Placing and finishing characteristics are improved because this admixture also retards setting time. Sika® Plastiment® R 168 admixture will not initiate or promote corrosion of reinforcing steel in concrete. The admixture does not contain intentionally added calcium chloride or chloride-based ingredients.
