E.M.AIR

DOSAGE

The rate of use of an air-entraining admixture depends on the air content (4–6 % typically) to be obtained along with many other factors.

The optimum dosage of E.M.AIR can be determined by trials in the site. Depending on concrete mix design (sizes and types of aggregates, cement content, water/cement ratio, ambient temperature and concreting conditions), a dosage of between 0.1 and 0.4 percent by weight of cement or cementitious material is recommended.

For use with other range of dosage, contact ABADGARAN GROUP Technical Services Department.

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

DIRECTION OF USE

1- E.M.AIR could be added to a part of concrete mixing water then added to the concrete mixture.

2- E.M.AIR could be added to ready-mixed concrete before placing concrete.

3- Admixtures must be weighed carefully.

ADVANTAGES

•  Increases freeze/thaw damage resistance.
•  Improves permeability and durability.
•  Improves harsh mixtures.
•  Improves concrete consistency (plasticity and workability).
•  Cohesion of mixtures is improved and bleeding reduced.
•  Eliminates segregation.
•  Ready to use - no dilution is required.

APPLICATION

• Workable and durable concrete for dams and reservoirs, tunnels, mass concrete structures, roads, runways, taxiways and etc.
•  Air-entrained concrete in cold weather condition.
• Pre-cast concrete sections.

STORAGE

• Shelf life: 1 year in the original package.
• Storage condition: should be protected from direct sunlight and frost. Keep container in the temperature range between +10 and +30°C.
• Packing: 20 kg container.
