DEZOMIX 4800
MODIFIED SILICA FUME GEL
DESCRIPTION
DEZOMIX 4800 is a modified silica fume gel which improves the rheological properties of concrete. It is based on a highly pozzolanic materials that can significantly reduce water absorption and increases the compressive strength of concrete.
DEZOMIX 4800 comprises the following chemicals:
- Silica fume
- Super plasticizer
This product can be evaluated using the following standards:
ASTM C1202,
BS EN 12390-8, BS 1881-122
APPLICATION
- High Strength Concrete (HSC)
- Water Resistant Concrete (WRC)
- Concrete in marine environments or exposed to chemical attacks
- Water and waste water treatment plants
- Piers, bridges, water tanks, etc.
ADVANTAGES
- Good reduction in water:cement ratio
- Good Improvement in workability & pumpability of concrete
- Reduction in cement content of concrete
- Compatible with all types of Portland cement
- Increase compressive strength of concrete
- Eliminates water absorption
- Considerable reduction in concrete permeability
DOSAGE
The optimum dosage of DEZOMIX 4800 can be determined by trials in the site. Depending on concrete mix design (concrete type, workability, compressive strength, size and type of aggregates, cement content, water/cement ratio, ambient temperature and concreting conditions), a dosage of between 5.0 and 9.0 percent by weight of cement is recommended.
For using a dosage out of the above-mentioned range, contact CONCRETE CLINIC OF IRAN Technical Services Department.
Please contact Technical Services Department in case of simultaneously use of more than one admixture.
DIRECTION OF USE
DEZOMIX 4800 can be added to concrete in two ways:
1- DEZOMIX 4800 could be added to ready-mix concrete before placing concrete.
2- DEZOMIX 4800 could be added to whole or a part of mixing water then added to the concrete mix.
