«HIDETAL-GP-9» beta «V»

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

Description

The additive possesses a complex of properties:

The basic properties – water reduction, a plastification, preservation of initial mobility of a concrete mix;

Additional properties - increase of frost resistance and watertightness of concrete;

Mobility increase б/с П1-П5, ОК> 25сm, РК> 63сm
Water flow reduction From 25 % and more
Reduction of the expense of cement To 25 %
Set the strength More than 60 % for 3 days
Frost resistance Increase at 2 marks and more
Watertightness Increase at 4 steps and more
Interaction with armature Passivirovanie armatures






















   
* - At use of the water reduced structure, concerning the telltale.

Sphere of application

  • All types of concrete, including prestressed concrete and reinforced concrete, in particular:
  • By manufacture of commodity concrete to which demands on a conservability of mobility of a concrete mix to 2,5-th hours inclusive are made;
  • At concreting thickly reinforced designs;
  • At manufacturing of self-condensed concrete;
  • By manufacture of products on rigid concrete mixes;
  • By manufacture of products to which increased requirements on frost resistance or water tightness are shown;

Advantages

  • Owing to the lowered dosage of introduction - a cost of transportation decreases;
  • For the account of high water reducing ability allows considerably (on 25 % and more) to reduce the expense of cement with an exit to branded durability **;
  • Reduces or completely excludes water partitioning off and an exfoliation on highly mobile mixes;
  • At use lasticizer effect - reduces time of vibrating of products, facilitates concrete consolidation. In a complex with additional actions allows to raise quality of a surface essentially;
  • Raises water tightness and frost resistance of concrete;
  • Short-term congealing at storage is supposed, - at thawing does not change properties;
  • The additive not горюча. It is not fetid, - possesses an easy technical smell;
  • At long storage in capacities does not drop out in a deposit.

** - Value depends on a quality class, properties of cement and some other factors.

The dosage and administration of supplements

From 0.2 to 0.54 % by weight of cement on a liquid substance additives. The introduction of a higher dosage of the additive insignificantly increases the mobility of a mix (see figure 1), but in this case requires additional rebounds for exceptions contain a lot of water.

In dosage of the additive in volume by weight of cement additives it is desirable to adhere to the following order: First calculate the weight of the additive on the basis of a bookmark of cement. Next, can be calculated: the Amount of additives(l) = Mass supplements(kg) / Density of the additive (the Exact density of the additive is indicated in the passport at a party or on the label).

Is introduced together with the mixing water.

Not to introduce into the dry mixture!

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 "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.

 with SDO or  SNV - to improve air entrainment;

Warranty and storage conditions

Warranty period of storage - 1 year from production date. After expiration, the additive may be applied to destination, after laboratory tests.

For storage conditions of special requirements. It is desirable to exclude long-term direct insolation and freezing containers with the additive. After a freeze additive can be used after a slow defrost at room temperature, with the subsequent hashing.

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.

         All tests use the following compositions:

Analysis of the increase frost resistance and impermeability

In the study of cold resistance and water resistance was used additional compound that is used to study the properties of the water-reducing additive.

Frost resistance is tested by the "third" accelerated method:
