Additive Kratasol-Crio-P "Extra" is a complex product including polymethylene (3-naphthalenesulfonates of different molecular weight, inorganic electrolytes, polyhydric alcohols.) Thanks to the rational combination of superplasticizing and antifreeze components, Kratasol-Cryo-P "Extra" prevents the concrete from freezing Transport up to the moment of laying, provides a normative set of strength at negative temperatures down to -25 ° C. For consumer properties, the additive Kratasol-Crio-P "Extra" corresponds to Requirements of GOST 24211, applied to superplasticizing, water-reducing, antifreeze additives.


Additive Kratasol-Crio-P "Extra" is intended for the production of ready-mixed concrete and mortar in winter conditions in order to prevent their freezing during transportation until the moment of laying, in order to ensure a normative set of strength at negative temperatures.


  • The possibility of concreting before the beginning of the heat treatment in conditions of design temperatures of hardening of concrete to minus 25 ° C;
  • Fast set of concrete strength with additives Kratasol-Crio-P "Extra" allows to reduce the time of removal of formwork;
  • It reduces the cost of electric heating;
  • Stable plasticizing effect when working on cements of various mineralogical composition (increasing the mobility of the concrete mixture from P1 to P5);
  • It does not contain chlorides and can be used in the manufacture of reinforced and prestressed reinforced concrete structures;
  • Does not reduce the protective properties of concrete in relation to steel reinforcement;
  • Does not increase the tendency to stress corrosion cracking;
  • Do not contribute to the formation of vysokolov.

Recommendations for use

Kratasol-Cryo-P "Extra" is introduced into the concrete mixture together with the 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, for preparing concrete mix, use heated water, while the recommended temperature of the concrete mixture at the outlet of the mixer is +15 ͦ + 25 0 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 necessary to provide measures to achieve not less than 20% of the strength from the design by the time the concrete is cooled down to the temperature at which the dosage of the additive is calculated.


The dosage of the additive is selected in each specific case by carrying out tests in laboratory and production conditions. The dosage of the additive depends on:

  • Brand strength of cement;
  • Chemical-mineralogical and material composition of cement and, accordingly, speed of cement strength;
  • Ambient temperature;
  • Temperature of the concrete mixture at the outlet of the concrete mixer;
  • Conditions of care for concrete;
  • Formulations of concrete mix: at a cement consumption of less than 350 kg / m 3 , an increase in the dosage of the additive is recommended.

In the case of long-term storage or use of large amounts of additives, periodic homogenization of the additive solution by bubbling with compressed air or stirring is necessary. Dosage should be carried out with an error of ± 2%.

Recommended dosage range depending on ambient temperature

The range of recommended dosages 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


In liquid form, the additive is supplied in bulk in auto- and railway tanks, as well as in plastic containers of various capacities. Kratasol-Cryo-P "Extra" is a non-toxic and non-flammable product. The additive is transported by any mode of transport, in accordance with the regulations in force.


Store in an environment that prevents the ingress of foreign objects, atmospheric precipitation. In the case of the freezing of the aqueous solution of the additive after thawing and homogenization, Kratasol-Crio-P "Extra" 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.


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.
