Descriptio

MASTERPEG 1200, is a highly water-reducing superplasticizing concrete additive based on polycarboxylate developed for prefabricated applications where the time between concrete production and its placement in the mold is short.

Field

• Non-decomposable concrete applications

• Low water/cement concrete

• Precast concrete requiring high early development

Features

• MASTERPEG 1200 which is the new generation of additive for super plasticizing concrete, ensures high maneuverability without causing segregation on fresh concrete.

• The product offers high initial strength to hardened concrete and allows for rapid demoulding.

• The product allows a significant reduction in construction time. Thanks to these properties, MASTERPEG 1200 is a suitable additive for precast concrete.

• The product does not contain chloride ions. It does not cause corrosion of the reinforcements.

• The product increases the hardness of the hardened concrete against frost.

Utilisatio

• The product increases the impermeability of concrete.

• MASTERPEG 1200, is ready to use as a liquid for mixing fresh concrete. It is recommended to add it to the wasting water in the ready-mix concrete production plant.

Standards

• MASTERPEG 1200: EN 934-2 Table 3.1, 3.2 ASTM C 494 Type F

Quantity of use

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 0.4% and 2% by weight. This rate changes in the design of the concrete mixture 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 MASTERPEG 1200, is a high-performance superplasticizing additive, the rates of use on the construction site and / or in the installation must be very well adjusted, in particular the over-incorporation of mixing water into the concrete mixture should be avoided.

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 on sale as a 25 kg plastic drum, 200 kg drums, 1000 kg plastic cubicles, and bulk.

Compatibility

MASTERPEG 1200 is compatible with PLASTPEG, Airpeg, Antipeg, Retardpeg, Proofpeg, Specialpeg series from PEGASUS. If more than one additive substance is used in the design of the mixture, each substance must be added to the mixture separately. It can be used with all types of cement compatible with masterpeg 1200, EN 197-1 and all mineral additives. For use on special types of cement, it is recommended to consult the PEGASUS Technical Support Unit.

Precaution of use

Contact of the additive with the skin and eyes should be avoided. In case of contact, wash with plenty of water. In case of contact with the eyes, wash immediately and thoroughly with water and consult a specialist. Safety glasses / gloves / protective masks should be used during the use of the mixture. The Material Safety Data Sheet (MSDS) should be read for detailed information.
