SikaMix® HC-300

Plasticizing Admixture

SikaMix® HC-300 is a specially formulated plasticizing admixture for drycast concrete application. SikaMix® HC-300 provides significantly improved cement dispersion. This results in increased compressive and flexural strengths, faster production rates and improved surface finish characteristics.

  • Increases the density of concrete products.
  • Reduces water absorption.
  • Increases the durability of concrete.
  • Increases efficiency of dispersion and distribution of cement, additives and pigments.
  • Reduces variations in density and strength across the area of the concrete mold.
  • Improves early and final strength of concrete.
  • Improves texture, smoothness and surface finish of concrete.
  • Increases machine productivity by enabling rapid filling of form and mold boxes.
  • Extends life of molds, minimized friction between the mold and the concrete.
