Sikacrete® PP1

MINERAL ADMIXTURE

Sikacrete® PP1 is a concrete admixture of the new generation in powder form, based on the Sika Silica Fume Technology.

Sikacrete® PP1 contains extremely fine (0.1 μm) latently reactive silicone dioxide. The presence of this substance gives greatly improved internal cohesion and water retentivity. The concrete becomes extremely soft and the pumping properties are substancially improved. In the hardened concrete the latently reactive silica fume forms a chemical bond with the free lime. The additional crystal formation produces a significantly more dense cement matrix.   Sikacrete® PP1 is used in combination with Sikament® superplasticizer, the performance characteristics of concrete will be improved in the following ways :
  • Increased workability over a longer period of time
  • Green concrete exhibits excellent stability
  • Durability is greatly increased
  • Water permeability of set concrete is much reduced
  • Vapour permeability is much decreased
  • High resistance to carbonation
  • Infiltration of chlorides is very much reduced
  • Very high early and ultimate strengths
  • Reduced deteriortion of migration due to chloride and sulphate reaction
Sikacrete® PP1 does not contain chlorides, nor other potentially corrosive substances. It, therefore can be used with complete safety in steel or fibre-reinforced and prestressed concrete.

Usage

Sikacrete® PP1 is used in structural concrete, precast processes, and other fields of concrete constructions to increase the density, durability and compressive strength of concrete.

Specific Advice

Concrete modified with Sikacrete® PP1 should be placed in the same way as normal concrete of moderate to high-slump consistency. Where Sikacrete® PP1 is used, the concrete mix must be prepared and placed in accordance with the standard rules of high durability concrete practice, and proper curing procedures must be initiated immediately after placement.

Application

Application Information

Dispensing

Sikacrete® PP1 is added to the dry ingredients at the batching/mixing plant prior the adding of the gauging water. A mixing time of 90 seconds is recommended to ensure uniform dispersion of Sikacrete® PP1 throughout the mix.The amount of water added should be adjusted according to the dosage of Sikacrete® PP1, Sikament® and the final required consistency. Other Sika concrete admixtures might be incorporated as well, if required for special performance characteristics.
Consumption

Recommended Dosage

5-10% by weight of cement.
