PUMKRET
HIGH PERFORMANCE ACCELERATING SILICA FUME GEL
DESCRIPTION
PUMKRET is an advanced concrete admixture 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, besides increasing workability and improving pumpability.
PUMKRET comprises the following chemicals:
- Pozzolanic materials
- New generation super plasticizers
- Waterproofing agents
- Suitable rheology modifiers for concrete
This advanced-technology product meets the requirements of the following standards:
ASTM C1202
BS EN 12390-8, BS 1881-122
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.
- Reduces water-cement ratio.
- Reduces cement content in concrete.
- Increases workability and workability retention of concrete.
- Improves pumpability of concrete and reduces depreciation of concreting equipment.
- It can be used with all types of Portland cement.
- Increases the compressive strength of concrete about 20%-50%.
- Considerably reduces permeability.
- Reduces the potential for AAR (Alkali-Aggregate Reaction).
- Inhibits chloride ion penetration and any other destructive chemicals influence.
- 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.
