PJSC Pigment offers innovative manufacturers Kratasol-Crio PC - a highly effective additive for winter concreting, operating at low dosages.

Kratasol-Crio PC - complex antifreeze additive based on polycarboxylates, systems of antifreezes, accelerators of hydration of cement, modifiers, rheological additives. Kratasol-Crio additive complies with the requirements of GOST 24211 for superplasticizing, super-reducing, antifreeze additives.

Applications

Kratasol-Crio PC is used for winter concreting at temperatures up to minus 25 ° C in the manufacture of:

  • Ready-mixed concrete;
  • Reinforced concrete products and structures, including prestressed;
  • Self-compacting concrete;
  • Thickly-reinforced structures;
  • High-strength concrete;
  • Concrete with high requirements for frost resistance and water resistance.

Benefits

  • Low dosages of the additive (for medium-aluminate cement - 0.5-5-1.5% for commercial product by weight of cement).
  • Allows you to transport concrete mixtures for 2 hours or more.
  • It allows concreting at temperatures up to -25 ° C.
  • High water-reducing effect (more than 20%).
  • It does not contain chlorides and can be used in the manufacture of reinforced and prestressed reinforced concrete structures.
  • Low dosages and a minimum amount of electrolytes can be effectively combined with electric heating.

 

  • Does not reduce the protective properties of concrete in relation to steel reinforcement.
  • Does not increase the tendency to stress corrosion cracking.
  • Does not contribute to the formation of the suns.
  • The additive improves water resistance (W12 and above).
  • It does not freeze at temperatures down to -25 ° C.

Recommendations for use

Kratasol-Criyo PC is introduced into the concrete mixture together with mixing water, preferably with the last third of the mixing water. It is not recommended to add the additive to the dry mix. After adding the additive to the solution, it is necessary to ensure sufficient mixing time for a uniform distribution of the additive in the concrete mix. It is advisable to comply with the requirements for work in winter: heating aggregates before use, to prepare the mortar mixture, use heated water, while the temperature of the solution mixture at the outlet from the mixer should not exceed + 35 ° C; Cleaning of the surface of the installation from snow and ice; In case of snowfall, use special shelters. To obtain the necessary strength characteristics of concrete, it is recommended that the requirements of SNIP 3.03.01 for the care of concrete in winter concreting are met. It is recommended to provide conditions for a concrete strength set of more than 20% from design to freeze.

 

Dosage

The dosage of the additive depends on the chemical-mineralogical composition of the cement, the quality of the aggregates, the type of the mortar mixture, the ambient temperature, and the intensity of mixing of the solution mixture. The recommended dosage range of the additive is 0.5-5-1.5% by product based on the weight of the cement. The dosage range of the additive can be extended. The optimum dosage of the additive is established during laboratory selection. In this case, the selection of the concrete composition is made in accordance with GOST 27006 by any method that meets the design requirements for concrete mixtures.

Physicochemical Properties

Transportation

In liquid form, the additive is supplied in bulk in auto- and railway tanks, as well as in

Plastic containers of different capacities. Kratasol-Cryo PC is non-toxic and

Non-flammable product.

The additive is transported by any mode of transport, in accordance with the current

Rules.

Storage

Store in an environment that prevents the ingress of foreign objects, atmospheric precipitation. In the case of freezing of the aqueous solution of the additive after thawing and homogenization of Kratasol-Cryo, the PC can be used in accordance with the recommendations. Observance of the recommended conditions allows storing the additive within 12 months from the date of manufacture.

Precautions

It is recommended to use protective gloves when working with the additive. If the additive gets on your skin, you should wash it off with soap and water. Avoid contact with eyes. In case of contact with eyes, rinse immediately with plenty of water and consult a doctor if necessary. Dispose of the additive according to local regulations, do not pour into the soil, water, sewerage.

Recommendations for the use of the additive are presented on the basis of the available practical experience with proper storage and use. For more information, please contact the technical support service of PJSC "Pigment", direction - "Additives in building materials".
