Product Description

FARSIZAL AIR is water soluble, chloride free air entraining admixture it is to create stable microscopic air bubble through the concrete and mortar mixture.
FARSIZAL AIR increases the resistance, of concrete to freeze– thaw cycles scaling improving workability and reducing bleeding.

Standard Compliance

FARSIZAL AIR complies with:

EN 934-2-Table 5
ISIRI 2930- Table 6

General Properties

Anionic	Ionic nature
Yellow liquid	Appearance
8.5±1	PH
1.05± 0.02	Specific gravity
<500 PPM	Chlorides content (PPM)

Application

FARSIZAL AIR is recommended for all concretes exposed to cyclic freezing and thawing like:

Light weight concrete
Mass concrete
Paving concrete
Ready-mix concrete
Structural concrete
FARSIZAL AIR is suitable for all types of cement

Advantages

Provides a stable air void system with proper bubble size and spacing. The air void system protects concrete against damage caused by repeated freeze/ thaw cycles.
The air bubbles act as “Ball – Bearings” to greatly improve the plasticity and work ability of the concrete, making it easier to flow in to forms or be pumped in to place
Less mixing water can be used
Minimize bleeding and segregation
FARSIZAL AIR aids in finishing and produces more watertight concrete with a lower water-cement ratio
Increased resistance to scaling from deicing salts
Makes concrete more durable

Method of Use

FARSIZAL AIR is supplied ready for use and is completely miscible in water
It can be added in to the mixer at the same time as the mixing water
It should not be added directly to the cement or dry materials
FARSIZAL AIR may be added at the end of mixing process by dispensing equipment or it may also be added to the concrete in a drum of ready mix truck, it should be mixed at least 1 minute per m³ of concrete at high speed

Dosage

FARSIZAL AIR is normally dosed at a rate of 40 to 80gr per 100kg of cement and will generally entrain 3 to 6% air in concrete.
Higher dosages may be utilized for special conditions and applications.
Field-testing is recommended to determine the optimum dosage and effect on both plastic and hardened concrete properties such as: workability and workability retention, setting time, early and ultimate strength.

Factors influencing amount of entrained air and dosage rate

The amount of FARSIZAL AIR required to obtain a given air content will very widely depending on:

Particle shape and grading of organic the aggregate used.
Impurities in the aggregate and hardness of water.
Fineness of cement
Amount of alkali in cement.

Effect of materials and proportions on air content

Guidance	Effect	Material
Increase FARSIZAL AIR dosage rate	Decrease in air content with increase in cement	Cement content
Adjacent FARSIZAL AIR	Air content increases with increased fineness of cement	Fineness of cement
Adjacent FARSIZAL AIR	Air content increases with increase in cement alkali content	Alkali content
Reduce dosage of FARSIZAL AIR	Air content increases with increase in dosage of lignin – based materials	Water reducers

Effects of material and construction variable on air content

Guidance	Effect	Variable
Run mixer close full, Avoid over loading	Air increases as capacity approached	Mixer capacity
Increase air-entraining dosage rate as temperature increases	Air content decreases with temperature increase	Temperature
Keep the pumping pressure as low as possible	Reduction in air content 1 to 2%	Pumping
Do not over vibrate avoid high- frequency vibrators (>10.000 vpm)	Air content decreases under prolonged vibration or at high frequencies	Internal vibration

Technical Advice

Following reduction of strength because of entrained air bubbles, it is recommended to use compatible water reduces in order to reduce the W/CM ratio.

Compatibility

With Cements

FARSIZAL AIR is suitable for use with cement replacement materials e.g. Fly ash, silica fume and blast furnace slag cement concrete.

With other Admixtures

FARSIZAL AIR should not be premixed or used with other admixtures unless receive the approval from manufacturer.

We would recommend that SHIMISAKHTEMAN be consulted in such circumstances.

Packaging

FARSIZAL AIR is supplied in 20kg gallons and 250kg drums.

Storage

FARSIZAL AIR Storage is recommended to keep within the range of 5°c to 40°c. If product has frozen, thaw and agitate until completely reconstituted.

Keep out of direct sunlight.

Shelf life

12 month when FARSIZAL AIR is kept under the recommended conditions and stored in unopened and undamaged original sealed containers.

Safety and Handling Precautions

FARSIZAL AIR is a low- hazard substance, it does not irritate skin and retina under normal conditions.

But in the line with general handling precautions to avoid contact with skin or eyes, protective gloves and goggles should be worn. .
