Kratasol PFM is a superplasticizing and superhardening additive for concretes and mortars based on polymethylene-3-naphthalenesulfonates and components that improve the performance properties of concretes and mortars. Kratasol PFM meets the requirements of GOST 24211, EN934-2, applied to superplasticizing, super-reducing, frost-resistant additives.
Kratasol PFM can be used for the production of:
The additive can be used for the production of high-strength concrete grade B40 and higher. Benefits
Recommendations for use
Superplasticizer Kratasol PFM 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 recommended dosage of the additive is 0,3-0,8% in terms of dry substance in relation to the weight of astringents or 1-2.3% of 35% solution. When working on medium-aluminate cement and ordinary aggregates in most cases, the range of dosages is 0.4-0.6% in terms of dry matter in relation to the mass of cement (1.1 + 1.7% 35% of the solution). 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, with subsequent adjustment of 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.
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).
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 Kratasol PFM superplasticizer can be used in accordance with the recommendations.
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" .
