SikaPaver HC 1

DESCRIPTION

SikaPaver HC 1 -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.

USES

▪ Concrete Pavers/Block Paving
▪ Masonry blocks
▪ Kerbstones
▪ Concrete pipes and manholes
▪ Concrete Roof-tiles

CHARACTERISTICS / 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
