SikaPaver®-740
(former MasterCast® 740)
HIGH PERFORMANCE COMPACTION AID FOR MANUFACTURED CONCRETE PRODUCTS
SikaPaver®-740 is a high performance compaction aid for manufactured concrete products, especially designed for even mould filling behaviour in combination with swipe formation at the concrete element flanks. Suitable for use in hot and tropical climatic conditions.
SikaPaver®-740 has been designed especially for the application in manufactured concrete products, and it causes:
- Better dispersion and wetting of cement, additives and pigments
- Reduced friction between cement and aggregates
- Introduction of small, evenly distributed air pores
- 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
- 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
