COMPLEX K-1

Hydrophobic admixture that does not block cement hydration.
Provides concrete water impermeability (up to W12 in combination with K-5 and K-17). Together with controlled air entrainment, it is used in stiff mixes and allows concreting under water at limited flow velocity.

Purpose:
Used in ready-mix, precast, road, and hydraulic concretes, industrial floors, complex mortars, gypsum systems, paving blocks, and vibropressed products.

Application:
Add to the concrete (mortar) mix as a component together with mixing water. Stir before use. The amount of admixture is calculated according to the dosage (see below). Further concreting or mortar use is carried out in the standard technological process.

Dosage:
The admixture should be dosed for cement systems, concretes, and mortars in the form of a ready-to-use aqueous concentrate, supplied in its original container.

Consumption is set from 1.5 L per 100 kg of cement.
The optimal dosage is determined in the laboratory for each specific case. The most effective method is adding the admixture to the mix together with mixing water, including through the water dispenser. Pre-dilution with water does not impair the performance of the admixture, but requires recalculation of the consumption relative to the concentrate.

Recommendations:
The dosing container must be clean and provide precise measurement of the dosing volume.

Safety Instructions:
Avoid ingestion or contact with food. In case of eye or skin contact, rinse thoroughly with water.

COMPLEKS K-3

Complex plasticizer additive with a retardation effect at ambient temperatures up to +25 °C and an accelerating effect in cold conditions.

Purpose:
Used for preparing cement mixes, ready-mix, precast concretes, and reinforced concretes.

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, at a rate of 1 L per 100 kg of cement. It is recommended to add it together with the mixing water using a water dispenser. Pre-mixing with water does not reduce the quality of the additive. 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.

COMPLEX K-5

Plasticizer and Accelerator with Antifreeze Effect
Acts as a hardening accelerator and setting intensifier, reducing curing time. Provides up to 20% strength gain at 1 day and up to 12% at 28 days.

Purpose:
Used as a plasticizer with antifreeze effect for concreting under direct freezing down to -7 °C, and with preheated aggregates down to -10 °C, with mandatory subsequent curing (the “thermos” method).

Application:
Add to the concrete (mortar) mix as a component together with mixing water. Stir before use. The amount of admixture is calculated according to the dosage. Further concreting or mortar application is carried out using standard technological procedures.

Dosage:
The admixture should be dosed for cement systems, concretes, and mortars in the form of a ready-to-use aqueous concentrate supplied in its original container, in the following amounts:

For direct freezing (down to -5 °C): from 3% of binder mass.
Under normal concreting conditions: from 1% of binder mass, together with mixing water through the water dispenser. Pre-mixing with water does not impair the quality of the admixture but requires adjustment of the consumption after dilution.

For mechanical dosing, it is best to add together with the mixing water through the water dispenser. Pre-dilution with water does not reduce admixture performance but requires recalculating consumption relative to the concentrate.

Recommendations:
The dosing container must be clean and provide precise volume measurement.

Safety Instructions:
Avoid ingestion or contact with food. In case of eye or skin contact, rinse thoroughly with water.
