SikaRapid®-1 Antifreeze-PK

COLD WEATHER CONCRETING ADMIXTURE

It is a safe and chloride free admixture in liquid form for producing high quality concrete while accelerating setting time at moderately low temperatures.

SikaRapid®-1 Antifreeze-PK provides the following properties:
  • ▪ Increased frost resistance
  • Improved strengths
  • It provides quickly achieving limit compressivestrength (4-5 N/mm²) that is necessary againstfreezing conditions and shortens this period.
SikaRapid®-1 Antifreeze-PK does not contain chlorides orother ingredients promoting corrosion of steel reinforcement. It is therefore suitable for reinforced concrete.

Technical Information

Concreting Guidance

The standard rules of good concreting practice for production and placing must be observed when using SikaRapid®-1 Antifreeze-PK in concrete. Refer torelevant 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

SikaRapid®-1 Antifreeze-PK is added to the gauging water at the plant or added onsite into the concrete mixer. When added separately to the freshly mixed concrete, further mixing should take place for at least 3 minutes. Before being discharged, the concrete must be visually inspected for even consistency.
Consumption

Recommended Dosage

1% by weight of cement (for 100 kg cement,  1000 g).
Application steps

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
