HP Retarder


HP Retarder is a water-reducing, set-retarding, concrete admixture in a concentrated form designed to increase compressive and flexural strengths in concrete mixes. Extended set times up to 2 hours or more (depending on the dosage added per bag of material) are typical with HP Retarder, as well as reduced drying shrinkage and reduced water absorption.
