* - When using water reduction  composition, relative to the control.

Sphere of application

         All types of concrete, including road concrete, in particular:

  • Concrete products and structures for the building of bridges, overpasses and underground transportation facilities;
  • Cement concrete pavement of highways;
  • Other construction of transport infrastructure;
  • In the manufacture of products on the hard concrete mixtures;
  • In the manufacture of all types of precast / concrete structures and concrete products of heavy concrete, including prestressed, strength class B25 and above;

Advantages

  • It is advisable to use in concrete class B25 from above with the mobilities of P1 to P5;
  • Due to the high water reducing capacity significantly reduces the consumption of cement with access to the brand strength;
  • Can significantly reduce the time and change the mode of TSS or to provide dual circulation forms in the day;
  •  Reduces or eliminates water separation and high-mobility bundle on mixtures;
  • When using a plasticizing effect - reduces the vibration of products facilitates compaction of the concrete. In combination with additional measures can significantly improve the quality of the surface;
  • Increases water-resistance and frost resistance of concrete;
  • A short-term freeze storage - thaw does not change behavior;
  • Additive is not inflammable. Not a stench - has a slight technical odor;
  • Long periods of storage in tanks does not precipitate.

The dosage and administration of supplements

From 0.6 to 1.5% by weight of the liquid cement additive substance.

When dosing additives in terms of the weight of the cement additives should adhere to the following order: First, calculate the weight of additives, based on bookmarks cement. Then you can calculate: Volume supplements, (l) = weight additives (kg) / density of the additive; (exact density additives indicated in the passport, by lot or on the label).

Introduced together with the mixing water.

Do not inject into the dry mix!

The best effect is achieved with the introduction of additives to the third part of the mixing water. That is, mixed concrete is mixed in full ingridientnom format with two thirds of mixing water. The third portion of water is mixed with metered amounts of additive injected into the mixer. Thereafter, stirring should continue for at least 60 seconds.

Compatibility with other products

Manufacturer investigated compatibility only with the products' SKT-standard. " Compatible with products of other manufacturers - has not been tested.



"HIDETAL-GP-9" alpha "B" compatible:

with "HIDETAL-P-7" - concrete hardening accelerator according to the dosage of the latter;

with "HIDETAL-P-8" - air-entraining agent to increase the F and W.;

Warranty and storage conditions

Shelf life - 1 year from date of manufacture. After expiration, the additive can be used as intended, after laboratory testing.

For storage conditions of special requirements. It is desirable to avoid prolonged direct insolation and freezing containers additive. After freezing, the additive can be used after a slow thawing at room temperature, followed by stirring.

The effectiveness of additives

The following are excerpts from:

  • Scientific and Technical Report on testing NIIZhB additive "HIDETAL-GP-9" alpha "B" and "HIDETAL-GP-9" beta "road" to comply with GOST for road concrete, conducted in 2010.
  • Scientific and Technical Report NIIZhB on complex series of tests supplements "HIDETAL-GP-9" alpha "and" HIDETAL-GP-9 "beta", carried out in 2007;
  • The first report was tested concrete composition class V40P4 with the introduction of 0.9% by weight of cement additives;

The second report used the following compositions:
