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
In hardened concrete, SikaPaver® HC-1 hence causes:
Higher concrete density and strength
Smoother and more homogenious concrete surfaces and flanks
