Extensive Testing Proves HuberCrete® Calcium Carbonate Performance and Strength
Extensive testing shows a replacement of either Type I or Type III cements with a HuberCrete® product has little to no affect on the fresh or hardened properties of precast concrete products. Huber’s testing at ambient and elevated temperature curing profiles used in precast, performed equally as the mix design without HuberCrete ground calcium carbonate.
HuberCrete offers improved workability in all types of concrete mixtures, from zero slump to high spread self-consolidating designs.
While HuberCrete is not pozzolanic, which describes a material that adds strength at a later curing time, it does offer an advantage for precast products by promoting the cement hydration reaction at a sub-micron level. The presence of the ground calcium carbonate particles provide a surface area of calcium that aids in the formation of the cement compounds as the cement reacts with water. This results in no impact on setting times and better green strength.

Guidance for using ground calcium carbonate can be found in the ACI 211.7R Guide for ‘Propor-tioning Concrete Mixtures using Ground Limestone and Other Mineral Fillers.’ HuberCrete offers particle sizes that allow the mix designer to take full advantage of the particle packing effect of the other materials in the concrete mix.
Precast products needing minimal bug holes should try HuberCrete® Extra Fine ground calcium carbonate. The particle size offers improved surface finish by contributing a particle smaller than the typical cement or fly ash particle in the particle packing matrix of the cementitious mixture.
