Plasticizers & Compaction Aid - 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.
Usage
SikaMix® HC-300 is recommended for use in all drycast concrete applications including, concrete blocks, pavers, segmental retaining walls, pipes, hollow core slabs and other drycast elements.

Application
Application Information
MixingSikaMix® HC-300 can be added with the batching water or introduced at the end of the mixing process. The concrete must be mixed for sufficient time to enable the uniform distribution of the admixture throughout the concrete. Do not introduce SikaMix® HC-300 up front, or directly onto dry cementitious materials, as this may reduce admixture performance.
Consumption
Recommended DosageDosage rates will vary according to materials used, ambient conditions and the requirements of the concrete. Sika recommends dosage at 2-10 fl. oz. per 100 lbs. (130-650 ml/100 kg) of cementitious materials for drycast concrete applications. Dosage rates outside the recommended range may be used where specialized materials are specified, extreme ambient conditions are encountered or unusual project conditions require special consideration.
