OptiFlo® 100R is a hydroxycarboxylic acid (HC) based set retarding, water-reducing admixture for concrete. It is has been carefully designed to provide uniform control of cement hydration, heat evolution, concrete plasticity and concrete set time. This unique product is a valuable tool to control both plastic and hardened concrete properties.

Placing and finishing crews benefit from longer working times and better finishing characteristics of concrete improved with OptiFlo® 100R.

OptiFlo® 100R slows the early hydration process that occurs when Portland cement is mixed with water, providing controlled "pre-set" and higher concrete strengths.
(More psi per pound of cement)

OptiFlo® 100R improves surface paste qualities and superior finished product appearance.
