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
- Increased frost and de-icing resistance
