Complex additive for the production of precast reinforced concrete, lightweight concrete, and cement mortars. It accelerates hardening kinetics and provides cement and energy savings during product heating and even without heating.
Purpose:
Used to increase the workability of concrete mixes and to improve early and standard strength — up to 20% at 1 day and up to 12% at 28 days.
Usage:
Add to the concrete or mortar mix together with mixing water. Stir thoroughly before use. The amount of additive is calculated according to the dosage (see below). Subsequent concreting or use of mortars is carried out following standard technological procedures.
Dosage:
The additive should be dosed for cement systems, concretes, and mortars in the form of a ready-to-use aqueous concentrate in the container in which it is sold, in the following quantities:
- For precast reinforced concrete: from 0.9 % by weight of binder.
- For conventional ready-mix concrete in the cold season with subsequent curing: from 1.5 % by weight of binder.
- For direct freezing of concrete down to −10 °C: from 3 % by weight of binder.
Optimal dosage should be determined in the laboratory for each specific technological case.
For mechanical dosing, it is preferable to introduce it together with the mixing water using a water dispenser. Pre-mixing with water does not reduce the additive’s quality but requires adjustment of the additive amount after dilution.
Recommendations:
The dosing container must be clean and have a precisely fixed volume.
Safety rules:
Avoid contact of the additive with the mouth or food products. In case of contact with eyes or skin, rinse thoroughly with water.
