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

advantages:
In hardened concrete, SikaPaver® HC-1 hence
causes:
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
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
