SikaPaver® HC-1

High performance compaction aid for semi-dry concrete products

SikaPaver® HC-1 is a high performance compaction aid for semi-dry concrete, especially designed for even mould filling behaviour in combination with swipe formation at the concrete element flanks.

SikaPaver® HC-1 has been designed especially for
the application in semi-dry concrete and
causes:
  • Better dispersion and wetting of cement, additives and pigments
  • Reduced friction between cement and aggregates
  • Introduction of small, evenly distributed air pores
  This leads in fresh semi-dry concrete to the following
advantages:
  • Granular mould-filling properties also at higher water contents
  • Stronger compactability, which allows for example achieving shorter cycle time or higher concrete densities
  • Reduced adhesion between the face mix and the tamper head
  • Increased green strength (shape keeping) after immediate de-molding

In hardened concrete, SikaPaver® HC-1 hence
causes:
  • Higher concrete density and strength
  • Smoother and more homogenious concrete surfaces and flanks
  • Increased frost and de-icing resistance
  • Better durability
  • Less quality variations and consequently less second grade products

Application Information

Dispensing

SikaPaver® HC-1 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.

Restrictions

Before use suitability tests must be performed.
Sufficient compaction of base and face concrete 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-1 in wet cast concrete is not suitable.
