SikaMix® NP

COMPACTING-AID FOR DRY-CAST CONCRETE

SikaMix® NP is a new generation, synthetically manufactured, admixture for low and no slump concrete mixes. SikaMix® NP is a scientifically formulated blend of a nonionic surfactant, and a plasticizing and dispersing agent which lubricates low and no (zero) slump concrete mixes utilized in block,(dry cast) concrete products, and pipe production. The lubrication quality of SikaMix® NP improves cohesiveness, strengths,
uniformity, and compaction in non-plastic concrete resulting in a reduction of breakage or chipping.

SikaMix® NP is an integral concrete densifying admixture that acts as a cement dispersant and enhances the unit water content.
  • Machine productivity will be increased by more rapid filling of form and mold boxes.
  • The internal lubricating properties of SikaMix® NP reduce the wear on machinery and extends machine life. (Surface swipe will be more pronounced.)
  • Moisture absorption rates will be reduced.
  • Lighter colours will maintain a more uniform, consistent shade and general product appearance will be improved.
  • Edges on pipe and block will be sharper, more defined and less likely to chip.
  
SikaMix® NP contains no calcium chloride or any other intentionally added chloride containing ingredients. It will not initiate or promote the corrosion of steel in contact with the concrete.

Application

Consumption

Recommended Dosage

The recommended dosage range for SikaMix® NP is 130 to 390 mL/100 kg (2-6 fl.oz./100 lbs.) of cementitious material.

   
It is suggested that trial mixes be conducted in order to determine the required dosage for optimum performance with your concrete components.

  

Mixing

SikaMix® NP should be added after the cement and aggregates have been moistened for optimum dispersion and performance. SikaMix® NP is compatible with other Sika® admixtures. However, each admixture should be added separately to the mix.
