ABATARD-L

DESCRIPTION

ABATARD-L is a highly efficient set-retarding admixture which temporarily stops the chemical action of hydration, delaying the initial set in direct proportion to the dosage used.

It meets the requirements of the following standards:

ASTM C494/C494 M TYPE B EN 934-2 ISIRI 2930 Table 9 Normal 0 false false false EN-US X-NONE FA

Method

ABATARD-L could be added to a part of concrete mixture water then added to the concrete mix.
ABATARD-L could be added to the concrete mix during the mixing cycle at the same time as the water or the aggregate or it could be added to ready-mixed concrete before placing concrete.

Note: Admixtures must be weighed carefully.

Properties

Provides controlled setting time.
Suitable for use in tropical and hot climatic conditions.
Increases workability retention.
Enables production and transportation of concrete over long distances.
After the initial retardation, the rate of hardening proceeds at a rate.
Prevents surface cracks in concrete.
Minimizes the risk of cold joints.

Application

Hot weather concreting.
Mass concrete.
Produces concrete.
with fractured coarse aggregates.
Pumping concrete at long distances transportation.
Roller-Compacted Concrete (RCC) - i.e. use for dam applications.

Considerations

The retardation rate achieved is directly dependant on the dosage rate which in turn is influenced by sizes and types of aggregates, cement content, type of concrete, water/cement ratio and ambient temperature.

The optimum dosage of ABATARD-L should be determined by trials in the site. A dosage of between 0.05 and 3.0 percent by weight of cementitious materials is recommended. For use with other range of dosage, contact ABADGARAN GROUP Technical Services Department.

Note: Please contact our Technical Department in case of simultaneous use of more than one admixture.

Protection and Safty

This product does not contain any substances hazardous to human health and the environment. However, it should not be swallowed or allowed to be in contact with skin and eyes. In case of contact with eyes, rinse immediately with plenty of water. For further information refer to the material safety data sheet. ABATARD-L is not flammable.
