  • Antifreeze additive Cryoplast Extra
Cryoplast Extra additive belongs to the class of plasticizers with antifreeze effect. It is a complex product consisting of sodium salts of polymethylene naphthalenesulfonic acids with the addition of an anti-frost complex based on sodium formate. Application: Application of Cryoplast Extra additive is necessary in conditions of winter concreting. Thanks to the synergistic effect, which is formed due to the simultaneous action of plasticizer and antifreeze complex on concrete, the dosage of the additive is much less than that of conventional antifreeze additives (by a factor of 1.5 - 2). Cryoplast Extra can be used for both ready-mixed concrete and concrete products. The additive does not contain corrosive and harmful substances; the chloride ion content is not more than 0.1%. Use of Cryoplast Extra additive allows: Work with concrete and mortar at an average daily temperature of minus 15 ° C; Provide a standard set of strength in accordance with GOST 24211-91 item 3.1; Improve the plasticity of concrete mixtures at low temperatures; Virtually eliminate the formation of highs on the front surfaces of products. The mobility of mixtures at a dosage of 2% corresponds to a cone draft of at least P5. Appearance and properties: Additive Krioplast Extra is produced according to TU 2601-003-51831493-01 in dry and liquid form: in the form of water-soluble brown powder or aqueous solution of dark brown color, having a concentration of at least 32%. During storage, it does not emit harmful gases or vapors. Dosage: Allowable dosage of the additive is from 1 to 2.5% of the mass of cement in terms of dry matter. The dosage of Cryoplast Extra additive depends strongly on temperature. Recommended dosages for different temperatures are given in the table:
Air temperature, ° С

% of the additive

To 5°С 1,0
To 10°С 1,5
To 15°С 2,5
Note: It is assumed that the composition of concrete is standard in accordance with GOST 30459. Storage: Guaranteed shelf life of the additive Cryoplast Extra: in liquid form -6 months from the date of manufacture. Packing and delivery: In liquid form, the additive (moisture content no more than 68%) is delivered in bulk in railway or tank trucks of various capacities. Restriction on use: Additive Krioplast Extra - a substance moderately dangerous, 3rd class of danger according to GOST 12.1.007. When working with an additive, it is necessary to use personal protective equipment (overalls, safety shoes, goggles, mittens, "Petal" respirator). Do not recomendet to use in: In prestressed constructions; In structures subjected to dynamic loads; In structures located in the zone of variable water level and unprotected by waterproofing; In reinforced concrete structures located at a distance of not less than 100 m from high voltage power sources. RECOMMENDATIONS FOR USE Cryoplast Extras 1. BASIC PROVISIONS. These "Recommendations" regulate the use of the additive Krioplast Extra for heavy and lightweight structural concrete for the erection of monolithic concrete reinforced concrete structures, monolithic parts of prefabricated monolithic structures and embedment of joints of these structures, as well as in the manufacture of prefabricated concrete and reinforced concrete products and structures at negative temperatures hardening of concrete (to minus 15 ° С). Additive Krioplast Extra prevents the concrete mixture from freezing during transportation, laying, compaction before the active heat treatment. In the case of thermosetting for 1.5 to 2 days, the concrete must have strength of at least 30% of the design strength at the time of its freezing, In the case of active heat treatment (the temperature of the heated concrete is 50 - 60 ° C), 70% of the strength is achieved from the design in 12 hours. In the case of freezing the concrete mixture for 1 to 5 days, the concrete after thawing accumulates 30% strength for 3 consecutive days with hardening at positive temperatures. Concrete with Cryoplast Extra additive does not apply:
  • in conditions of constant exposure to atmospheric moisture of relative humidity of air more than 60%), if there are reactive silica in the filler;
  • In reinforced concrete structures and products for electrified transport and industrial enterprises that consume a constant electric current;
  • Prestressed structures, steel-reinforced classes: at-iv, at-v, at-vi, at-iv, at-v.
2. REQUIREMENTS TO MATERIALS.
  • Additive - Cryoplast Extra according to the quality indicators must comply with the requirements of TU 2499-002-51831493 "Plasticizing antifreeze agent C-3M-15. Technical conditions »;
  • For the preparation of concrete with the addition of Cryoplast Extra it is recommended to use Portland cements in accordance with GOST 10178;
  • Fillers for concrete must meet the requirements of GOST 26633, GOST 25820.
3. APPOINTMENT % OF ADDITIVES. Concrete with Cryoplast Extra additive meets the "Requirements for workability", strength, frost resistance, water resistance and other indicators selected by any conventional method; Recommended dosage of additive Cryoplast Extra

Air temperature, ° С

% of the additive

To 5°С 1,0
To 10°С 1,5
To 15°С 2,5
4. INSTRUCTIONS FOR USE. Cryoplast Extra should be dosed into a concrete mixer in the form of a solution of 35-36% (density 1.19 kg / cc, pH = 7.35) through the water dispenser, while reducing the water flow of hardening by 15-22%; Storage Cryoplast Extras should be stored in storage at a temperature of at least 10 ° C. In case of accidental freezing, C-ZM-15 (Cryoplast) does not decrease its quality parameters. Before use, the aqueous solution must be warmed up to t ~ + 10-15 ° C.
