SikaPaver®-2 HC KE

High performance compaction aid for semi-dry / no-slump concrete products

SikaPaver®-2 HC KE is a high performance compaction aid for semi-dry/no-slump concrete based on the Sika® ViscoCrete® technology. This innovative admixture technology has been specifically developed for use in low cement content semi-dry/no-slump mixes where good surface/flanks finish and high early strength are required.

SikaPaver®-2 HC KE offers substantial benefits to the producer of semi-dry/no-slump concrete products:
  • Efficient dispersion and distribution of cement, additives and pigments
  • Improved mould filling
  • Optimised compaction process Minimized friction between the mould and the concrete
  • Reduced adhesion/stickiness between top layer concrete and pressing head/tamper
  • Increased “green” strength after immediate demoulding
  • Less variation in densities and strengths across the area of the mould 
  • More economic concrete mix designs
  • Less customer returns and second grade products  
SikaPaver®-2 HC KE allows for the following advantages in the finished concrete products:
  • Closer textured, smoother and more uniform surfaces
  • Consistent product quality
  • Minimized damage due to early handling Enhanced early and ultimate compressive and tensile strengths
  • Increased freeze-thaw resistance
  • Improved durability and life expectancy

Usage

SikaPaver®-2 HC KE is used for all types of semidry/no-slump concrete which is generally used in the manufacture of machine-made concrete products associated with instant de-moulding such as:
  • Block Paving (grey / coloured)
  • Paving flags
  • Kerbstones Edgings and other items for garden and landscape design
  • Building blocks and bricks
  • Concrete pipes and manholes
  • Semi-dry hollow core slabs
