ARSTEP 20 Series

ARSTEP 20 SERIES products are naphthalene sulfonate / lignosulfonate based water reducing plasticizer concrete additives used to increase the workability and mechanical properties of concrete by reducing the water / cement ratio. Summer (S) type products have the feature of delaying setting (consistency protection) in hot weather. Winter (W) type allows concrete casting in cold weather conditions. In addition, the products in this product group are also available in concentrated form. ARSTEP 20 SERIES products have more water cutting and consistency protection features compared to other sub-series groups.

to application.

Application

Aggregates and the binder (cement-silica fume-fly ash-blast furnace slag) should be mixed until obtaining a homogenous mixture. After adding 70% of mixing water into the dry mixture, ARSTEP 20 SERIES products should be added into the rest of water and should be mixed properly. Warning: Concrete mix design and admixture dosage should be determined by laboratory tests according to the concrete class and properties.

Dosage

ARSTEP 20 SERIES products’ dosage should be adjusted according to the total amount of binder in the mixture design. This ratio varies according to the cement, aggregate, mineral additive, water components used in concrete mixture design and also the desired fresh and hardened concrete properties. Therefore, before determining the usage rate, laboratory tests should be made according to the properties expected from fresh and hardened concrete and the mixing ratio should be determined according to these tests.

Storage

Shelf life is 12 months from the date of production when stored in original unopened and undamaged packages (drums, barrels, IBC containers) at temperatures between +5 °C and +35 °C, protecting from direct sunlight, excessive heat and frost. If the product has waited for a long time, make it homogeneous by mixing it mechanically before using it. Make sure that the product does not freeze. If the product freezes, it should be thawed by keeping it at room temperature without using direct heat and mixed by mechanical methods until it becomes homogeneous.
