Polycarboxylate base additives in concrete, regulating the preservation of mobility of the concrete mixture.

Kratasol Flowret is a highly effective polycarboxylate base (produced by Pigment Pigment), designed to increase the mobility of the concrete mix.

AREAS OF USE

Kratasol Flowret - the basis of additives that regulate the conservation of mobility of the concrete mixture. Kratasol Flowret can be used as a component of complex plasticizing, water-reducing additives if it is necessary to increase the mobility of mobility of concrete mixtures.   

ADVANTAGES

  • Possibility of transportation of concrete mixes up to 5 hours using additives based on Kratasol Flowret;
  • Excellent compatibility with water-reducing polycarboxylates of Kratasol Flow. The possibility of obtaining, with the joint application of Kratasol Flowret and Kratasol Flowcast, concretes with a high mobility time and high early strength values, which is impossible with traditional moderators;
  • The possibility of modeling the behavior of a concrete mixture by changing the ratio of Kratasol Flowret brand A and Kratasol Flowret brand B.

RECOMMENDATIONS FOR APPLICATION

Additives are concentrated solutions of polycarboxylates of intrinsic synthesis that regulate the preservation of mobility of a concrete mixture. When designing the composition of additives based on Kratasol Flowret, it should be borne in mind that these additives at optimal dosages increase the mobility of the concrete mixture (depending on the dosage, materials used, water-cement ratio):

Kratasol Flowret brand A - 2-5 cm for 30-60 minutes

Kratasol Flowret brand B - 3-7 cm for 40-80 minutes

In this case, Kratasol Flowret brand B has a lesser hydrogen-reducing effect in comparison with Kratasol Flowret brand A (an average of 10% depending on the materials used).

In additives based on Kratasol Flowret, it is necessary to introduce defoamers to reduce the amount of air entrained in the concrete mixture. To determine the nature and the optimal dosage of defoamer, it is necessary to carry out laboratory tests, selection.

It is recommended to introduce additives based on Kratasol Flowret water-reducing polycarboxylates (Kratasol Flowcast) to achieve the necessary strength characteristics of concrete. The ratio between polycarboxylate, regulating the safety of mobility of a concrete mix, and water-reducing polycarboxylate is selected by laboratory selection depending on the materials used, requirements for concrete mix and concrete.

To increase the retainability of the mobility of the concrete mix, the consumption of the Kratasol Flowret additive is 0.1 ÷ 0.3% of the dry matter by weight of the cement. The dosage of Kratasol Flowret can vary both in the large and in the lower side, depending on the materials used, the requirements for the concrete mixture, and concrete. The optimal consumption of Kratasol Flowret additive is established during laboratory selection. To achieve the necessary quality indicators of concrete mix, concrete, economic effect, Kratasol Flowret should not be overdosed.

If it is necessary to further increase the frost resistance of concrete, it is recommended to share the additive on the basis of Kratasol Flowret and Aeromix.
