Highly effective superplasticizing and super-water-reducing additive for concrete and mortar based on polycarboxylate esters, modifiers. In terms of its consumer properties, the superplasticizing - super-hydrating additive meets the requirements of GOST 24211, EN934-2.

Applications

Superplasticizer Kratasol PC B grade is recommended for the production of high-mobility, self-compacting concretes, if necessary, to maintain the mobility of concrete mixes. Kratasol PC B makes it possible to produce concretes with high performance characteristics (strength, waterproofness, frost resistance), and due to the super-vortexing effect, the additive provides a high speed of recoating the strength of concrete. The additive can be used for the production of high-strength concretes of class B40 and higher.

Benefits

  • High water-reducing effect - more than 20%;
  • A pronounced plasticizing effect from P1 to P5 at low dosages (in many cases, 0.2-5-0.4% by dry matter from the mass of cement);
  • The use of the additive makes it possible to increase the strength of concrete by more than 25%;
  • The additive is combined with cement of various mineralogical composition;
  • Low dosage additives for obtaining high-strength concretes;
  • Allows to significantly save costs when laying concrete (additive allows you to reduce the vibration time or completely give up vibration when getting self-compacting concrete);
  • The additive provides high values ​​of early and final strength;
  • The additive provides a long time of preservation of mobility of concrete mixes;
  • The absence of chlorides allows the use of an additive for the production of reinforced and prestressed products.

Recommendations for use

Superplasticizer Kratasol PC grade B is introduced into the concrete mixture together with mixing water, preferably with the last third of the mixing water. Do not add 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 air entraining admixture TM KRTASOL Aeromix if it is necessary to regulate the air entrainment (obtaining transport concretes, etc.), giving the concrete mixture special rheological properties, etc. The additive is not compatible with products based on polymethylene naphthalenesulfonates.

Dosage

The recommended dosage of the additive is 0.5-1.5% of the liquid additive based on the weight of the binders. 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. 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 made with an error of ± 2%.

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 PC brand B is non-toxic and

non-flammable product.

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

rules.

Storage

Store at + 5 ÷ + 35 ° C in a closed 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 Kratasol PC B superplasticizer 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".
