SikaPaver®-798

(former MasterCast® 798)

New generation plasticizer for Manufactured Concrete Products

SikaPaver®-798 is an innovative multi-purpose plasticizer specially developed for semi-dry concrete mixes. The product is suitable for the production of blocks and pavers.
SikaPaver®-798 accelerates the strength development and reduces the cycle time whilst the appearance is maintained or even improved.
Due to its unique principle of action on the cement grain, SikaPaver®-798 fully exploits the hydration potential of cement, resulting in higher early strengths and shorter curing times.
Suitable for use in hot and tropical climatic conditions.  

SikaPaver®-798 offers the following benefits for the Manufactured Concrete Products industry:
  • Enhanced productivity due to shorter cycle time
  • Higher early strength
  • Enhanced curing cycles due to shorter curing times

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using SikaPaver®-798 in concrete. Refer to relevant standards.

Fresh concrete must be cured properly especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® products as a curing agent or apply wet hessian.

Application

Application Information

Dispensing

SikaPaver®-798 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.

Compatibility

SikaPaver®-798 is suitable for mixes containing all types of cement and supplementary cementitious materials such as Microsilica (Silica Fume), Fly Ash (PFA), GGBS (Ground Granulated Blast Furnace Slag) and the following Sika products:
SikaPlast®, Sika® ViscoCrete®, Sikament®, SikaPump®, Sika® FerroGard®, SikaFume®, SikaFiber®, Sika® Aer, Sika® Stabilizer, SikaControl®
We recommend to perform trial mixes to establish the required performance when combining SikaPaver®-798 with the above products or other admixtures. Please consult our Sika Technical Department.
Consumption

Recommended dosage

0.3 - 1.0 % by weight of binder.
Dosages outside of this range can be used depending on the mix design, raw materials, climatic conditions and concrete requirements. Trial mixes must be performed to establish the exact dosage rate required.
