ARSTEP EXTRA 300 Series

• ARSTEP EXTRA 300 SERIES products are recommended to be added to the mixing water in ready-mixed concrete production plants. It should not be added directly to the dry mixture.
• If it is added directly to fresh concrete, the mixing time should be extended for at least 1-2 minutes at fast speed to ensure sufficient homogeneity or this time should be determined in laboratory trials.
• When more additives are used than the specified range of use, it may affect the setting time of the concrete. In such cases, a preliminary test should be done in the laboratory.

Usage according to weather conditions;

• In Summer: Arstep Extra 300 S     • In Winter: Arstep Extra 300 W     • At Normal Temperature: Arstep Extra 300

ARSTEP EXTRA 300 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.

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 EXTRA 300 SERIES products should be added into the rest of water and should be mixed properly.
