SikaPaver HC-1

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.

Advantages

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
