SikaPaver®-803

New generation of polycarboxylic ether-based plasticizer for Manufactured Concrete Products,                                                                                                                                                                                 specially engineered for use in production hollow-core slabs and masonry

SikaPaver®-803 is an innovative multi-purpose plasticizer based polycarboxylic ether polymers specially developed for semi-dry concrete mixes. The product is suitable for the production of hollow-core slabs and masonry.
At the same time, SikaPaver®-803 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®-803 fully exploits the hydration potential of cement resulting in higher early strengths and shorter curing times.
Suitable to use in hot and tropical climatic conditions.

SikaPaver®-803 offers the following benefits for the MCP industry:
  • Optimised mix design
  • Enhanced productivity due to shorter cycle time
  • Higher early strength
  • Optimised curing cycles due to shorter curing times
  • Possibility of using recycled aggregates
  • Fair-faced hollow blocks

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using SikaPaver®-803 in concrete. Refer to relevant standards.

Application

Application Information

Dispensing

SikaPaver®-803 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®-803 is compatible and recommended for use with:
SikaPaver® WP 240, water repellent and efflorescence control admixture

We recommend to perform trial mixes to establish the required performance when combined with the above products. Please consult our Sika Technical Department.
Consumption

Recommended dosage

0.4 - 1.2 % 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.
