Admixture for concrete products

Product Description

QUANTEC® ULTRA-ES admixture is a high performance cement dispersant based on a patented technology. It has been formulated as a ready-to-use liquid for use in the production of architectural concrete block, concrete pavers and segmental retaining wall units.

Product Advantages

  • Improves cement utilization
  • Reduces feed and finish times
  • Increases compressive and strengths
  • Reduces culls

Product Uses

QUANTEC® ULTRA-ES admixture is a superior dispersant with a marked capacity to break up the cement agglomerates normally found in high cement content, dry-cast concrete mixtures.

The resultant increase in available cement surface area enhances the efficiency of cement hydration, producing units with reduced paste porosity and increased compressive strengths.

Application Information

QUANTEC® ULTRA-ES admixture is compatible with most concrete additives but when multiple additives are used they must be added separately to the concrete mixture.

Addition Rates

QUANTEC® ULTRA-ES admixture is used at a rate of 2-6 oz/cwt (130-390 mL/100 kg) of cementitious materials, including pozzolans. The addition rate is dependent upon the specific set of materials and the desired end properties.

QUANTEC® ULTRA-ES admixture produces little change to the appearance of the concrete units at the lower addition rates, but may provide a swipe/texture surface at the higher addition rates.

Mixing Procedure

For maximum product efficiency add QUANTEC® ULTRA-ES admixture to the prewetted aggregate or after the cement has been wetted out. Allow an additional 60-120 seconds mix time after all of the admixture has been introduced.


QUANTEC® ULTRA-ES admixture is available in drums and returnable totes.

Health & Safety

All precautions defined on the SDS (Safety Data Sheet) for QUANTEC® ULTRA-ES admixture must be followed.


QUANTEC® ULTRA-ES admixture will begin to freeze at approximately 32 ºF (0 ºC), but will return to full strength after thawing and thorough agitation.
