PUMKRET

SUPER PLASTICIZING / WATERPROOFING SLURRY WITH HIGHLY POZZOLANIC ACTIVITY FOR READY-MIXED CONCRETE

DESCRIPTION

PUMKRET is an advanced concrete admixture which improves the rheological properties of concrete and could be added to the concrete mixtures at the job site. It is used for designing high performance concrete and multipurpose concrete mixtures. PUMKRET is based on a highly pozzolanic mineral material which significantly reduces water absorption and permeability of concrete, In addition improves workability. High range water reduction is one of the most exceptional properties of PUMKRET.

PUMKRET comprises the following chemicals:

Pozzolanic materials.
Super plasticizer.
Waterproofing agent.
Suitable rheology modifiers for concrete.

It could be controlled by below mentioned standards:

ASTM C1202

BS EN 12390-8, BS 1881-122

Method

DOSAGE

The optimum dosage of PUMKRET can be determined by trials in the site. Depending on concrete mix design (concrete type, workability, compressive strength, sizes and types of aggregates, cement content, water/cement ratio, ambient temperature and concreting conditions), a dosage between 3.0 and 8.0 percent by cement weight is recommended.

Note: when using PUMKRET, water-cement ratio must be considered around 0.40

For using other ranges of dosage, contact ABADGARAN INTERNATIONAL GROUP Technical Services Department.

Please contact our engineering office in case of simultaneous use of more than one admixture.

DIRECTION OF USE

PUMKRET can be added to concrete in two ways:

1-PUMKRET could be added to ready-mix concrete before placing concrete.

2-PUMKRET could be added to a part or whole of concrete mixing water then added to the concrete mix.

Properties

ADVANTAGES

Reduces water-cement ratio.
Increases workability and workability retention of concrete.
Improves pumpability of concrete and reducing depreciation of concreting equipment.
Reduces cement content of concrete between 10 to 15 percent.
It can be used with all types of Portland cement.
Increases the compressive strength of concrete about 20%-50%.
Considerably reduces permeability of concrete.
Reduces chloride ion penetration and any other destructive chemicals influence.
Reduces the potential for AAR (Alkali-Aggregate Reaction).

Application

Improving the quality of concrete elements (Foundation, Deck, Column, Shear walls, etc.)
Enables production and transportation of concrete in long distances and hot weather concreting.
Produces High Strength Concrete (HSC) and Water Resistant Concrete (WRC).
Suitable for marine environments or the regions exposed to chemicals attack, e.g. southern and northern parts of Iran and saline regions.
Docks, deck bridges, tanks, etc.
Designs of concrete mixes for Water and Wastewater Treatment.
