Kratasol AF V grade (Kratasol AF m. V) is a highly effective additive for commercial concrete and mortar based on aliphatic ionomeric polymers, modifiers, moderators. Additive is the newest regulator of rheological properties of concrete and mortar mixes. The additive does not contain sulfates.

According to its consumer properties, Kratasol AF brand V meets the requirements of GOST 24211, EN934-2, applied to superplasticizing, water reducing, regulating the safety of mobility of concrete and mortar mixtures additives.

Applications

Superplasticizer Kratasol AF V grade is recommended for the production of commercial concrete, if necessary to ensure the preservation of mobility of concrete mixes. Kratasol AF V grade is also a structural modifier of concrete, which makes it possible to produce concretes with high performance characteristics (strength, water resistance, frost resistance). Superplasticizer Kratasol AF V grade can also be used for the production of mortar, lightweight concrete.

The additive is not a corrosive component of concrete, does not affect the protective properties with respect to steel reinforcement, does not cause its corrosion in the initial state and can be used in the production of reinforced concrete structures in residential and public buildings in accordance with SNIP 52-01 and SNIP 2.03. eleven.

Benefits

  • Stable plasticizing effect when working on cements of various mineralogical composition: increasing the mobility of the concrete mixture from P1 to P5;
  • Increases the strength of concrete by more than 20% compared to no-add concrete (when tested in an equidistant mixture);
  • Allows you to transport concrete and mortar mixes for 2 hours or more;
  • Absence of sediment at low temperatures;
  • Facilitates the pumping of concrete mixtures;
  • It does not contain chlorides, which makes it possible to use it in reinforced structures (including prestressed ones);
  • Increases water-bearing capacity and frost resistance of concrete;
  • Improves the adhesion of concrete with embedded fittings and metal products.

Recommendations for use

Superplasticizer Kratasol AF V grade 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 concrete mix, it is necessary to ensure a sufficient mixing time for a uniform distribution of the additive in the concrete mix. The additive is combined with the air entraining admixture TM KRTASOL Aeromix if it is necessary to regulate the air entrainment (obtaining transport concrete, higher frost resistance concrete, etc.), giving the concrete mixture special rheological properties, etc.

Dosage

The recommended dosage of the additive is 0.2-0.5% in terms of dry matter with respect to the weight of binders (or 0.6-1.5% of the weight of astringent liquid formulations). The range of recommended dosage supplements can be extended. The optimum dosage of the additive is established during laboratory selection. At the same time, the concrete composition is selected in accordance with GOST 27006 by any method that meets the design requirements for concrete and concrete mix, followed by adjusting properties by reducing water consumption and optimizing the dosage of the additive. It is recommended to dispense with an error of not more than ± 2%.

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.

Physicochemical Properties

Transportation

In liquid form, the additive is supplied in bulk in auto- and railway tanks, as well as in plastic containers of various capacities.

In dry form, the additive is packaged in paper or polypropylene bags with a polyethylene liner or soft containers such as MKR (big bags).

Storage

Store at + 5 ÷ + 35 ° C in a sealed container. Avoid exposure to direct sunlight. If the recommended storage conditions are violated, the physical, chemical and consumer properties of the product may change. Observance of the recommended conditions allows storing the additive within 12 months from the date of manufacture. In the case of the freezing of the aqueous solution of the additive after thawing and homogenization, the superplasticizer Kratasol AF V grade can be used in accordance with the recommendations.

Precautions

It is recommended to use protective gloves when working with the additive. If the product gets on your skin, 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 further information, please contact the technical support service of PJSC "Pigment" , direction - "Additives in building materials" .
