Descriptio

AIRPEG K is a ready-to-use air drive additive that results in a good distribution and size of air in concrete rods thanks to its special air drive components.

Domain

• In all categories of ready-mixed concrete described in EN 206 and EN 13515

• On concrete in which light aggregate is used

• In the production of ready-mixed wet plaster

• On concrete in which the unit weight is low

• On concrete that may be exposed to a freezing effect

• On concrete roads, canals, airport runways and concrete lots.

• On low-subsidence concrete

• On roller compacted concrete. Features

• It increases endurance against freezing and thawing by drawing air onto fresh concrete.

• It increases the maneuverability of fresh concrete and facilitates pumping.

• It prevents resolution, increases cohesion.

• It decreases the amount of mixing water without loss of maneuverability.

• It does not include chloride ions and it does not cause corrosion of the paraphernalia.

• It lets concrete mixing patterns form with low water/cement contents.

• It increases the endurance of hardened concrete against environmental effect conditions.

Utilisatio

• AIRPEG K is ready to be used as a liquid for mixing fresh concrete. It is recommended to add it to the mixing water in the ready-mix concrete production plant.

Amount of usage

It is recommended that the total binder existing in each type of concrete class mixture design described in EN 206 and EN 13515 be used between the rates of 0.05% and 0.20% in terms of weight. This rate changes in terms of concrete mix design depending on the amount of air required, the cement characteristics used, aggregates, mineral additives, water components, heat and also according to the preferred characteristics of fresh and hardened concrete. Therefore, laboratory tests should be carried out according to the preferred characteristics and the rate of use should be determined. Since the amount of air to be drawn into the concrete will increase the additive dosage to be used, it is expected that the strength of the concrete will decrease.

Storage conditions and

The product should be stored above 5 °C. In the event that the product freezes, it must be thoroughly mixed mechanically after thawing for restitution. It is offered for sale as a 25 kg plastic drum, 200 kg drums, 1,000 kg plastic cubicines and bulk.

Compatibility

AIRPEG K is compatible with PLASTPEG, Airpeg, Retardpeg, Proofpeg, Specialpeg construction chemicals from PEGASUS. The PEGASUS Technical Support Unit should be contacted for information on compliance with other additives. If more than one additive is to be used in the desired mixture design, each additive must be added separately to the mixture.

Precaution of use

Avoid contact of the product with the eyes or skin, in case of contact with them, rinse thoroughly with water. In case of contact with the eyes, wash immediately and thoroughly with water and then consult a specialist. Use gloves, a protective mask and goggles during use.
