SikaPaver® HC-218

Compaction aid for semi-dry concrete with improved mold filling properties

SikaPaver® HC-218 is a filling and compaction aid which has been designed to eliminate the stickiness of semi-dry concretes at elevated water-cement-ratios. The resulting granular concrete leads to an even mold filling and less quality fluctuations while ensuring the targeted concrete compaction.

  • Granular mold-filling properties despite elevated water contents
  • Even concrete distribution into the individual chambers across the compaction mold
  • Less quality variations and consequently less second grade products
     SikaPaver® HC-218 improves the dispersion and wetting of cement, additives and pigments and hence allows reaching the target density in shorter time or the reduction of pore content at the same compaction effort.

Application

Application Information

Dispensing

SikaPaver® HC-218 shall be added with the mixing water or introduced at the end of the mixing process.

The necessary mixing time after the admixture dosage depends on the individual mixer.

Compatibility

Before use suitability tests must be performed.
Sufficient compaction of base and face concrete while in parallel avoinding capillary porosity is essential to ensure the targeted performance parameters of the manufactured semi-dry concrete elements. For further information and advice, please contact our Technical Service Department.
The use of SikaPaver® HC-218 in wet cast concrete is not suitable.
Consumption

Recommended Dosage

0.2 – 0.5 M.-% of binder (cement and fly ash)
