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
  This leads in fresh manufactured concrete products 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®-740 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

Application

Application Information

Dispensing

SikaPaver®-740 is a liquid ready-to-use admixture to be added to the concrete during the mixing process. The best results are obtained when the admixture is added after all the other components are already in the mixer and after the addition of at least 80% of the total water. The water content is adjusted to obtain the desired consistence or workability.
Consumption

Recommended dosage

0.1–0.5 % by weight of binder

Other dosages may be used in special cases according to specific job site conditions. Please consult our  Sika Technical Department.
