«HIDETAL-GP-9» beta «A»

Superplasticizer 5th generation (giperplasticizer) on the basis
of ether polycarboxylates for concretes

Description

The addition has a set of properties:

The main properties – water reduction, lamination, maintaining the original mobility of the concrete mix;

Additional properties - increase frost resistance and impermeability of concrete;

Increased mobility of b / s P1-P5, OK> 25cm, 63 cm
Reducing water flow from 25% or more
Reduction in cement consumption up up  to 25%
Set the strength No more than 50% on the third day *
Frost resistance increase of 2 stamps and more
Water resistance increase of 4 stages and more
The interaction with the reinforcement reinforcement passivation





















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

Sphere of application

All types of concrete, including prestressed concrete and reinforced concrete, in particular:

  • In the production of ready-mixed concrete, which are requirements for persistence wet concrete up to 4 hours, inclusive;
  • When concreting thickly reinforced structures;
  • In the manufacture of self-compacting concrete;
  • In the manufacture of products on the hard concrete mixtures;
  • In the production of products, which are increased requirements for frost or water-tight;

Advantages

  • It is advisable to use in concrete class of B20 or higher;
  •  Due to the high water reducing capacity significantly (by 25% or more) to reduce the consumption of cement with access to the brand strength; **
  • 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.


** - This value depends on the type of concrete, the properties of the cement and some other factors.

The dosage and administration of supplements

From 0.6 to 1.5% by weight of the liquid cement additive substance. The introduction of a higher dosage of supplements insignificantly increases the mobility of the mixture (see Figure 1), but in this case, additional rope to avoid water separation.

When dosing additives in terms of the weight of the cement additives desirable to 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 supplements (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.

Safety and transportation

           The product is a 4-hazard class according to GOST 12.1.007 (moderately hazardous).

     Working personnel must use personal protective equipment according to GOST 12.4.011. Eye Contact - rinse thoroughly with water and, if necessary - see a doctor.

          Do not discharge into drains, soil or bodies of water! Disposal of supplements must be made according to local regulations.

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" beta "A" 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.

 with SDO or  SNV - to improve air entrainment;

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 Scientific Technical Report, published in 2012. Based on these data it is possible to obtain an overview of the properties of the additives, however, these properties may vary significantly depending on the composition of the concrete, cement properties and fillers.
