COMPLEKS K-2

Additive for precast and monolithic aerated and expanded clay concretes that accelerates hardening kinetics.

Purpose:
Used for preparing cement-based concrete and mortar mixes as a hardening accelerator with antifreeze effect down to -10 °C.

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.

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 quality of the additive 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.

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.

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.

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.

COMPLEKS K-6

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.

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.

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.

COMPLEKS K-7

Complex plasticizer and accelerator additive for ready-mix and precast concretes. The additive increases both early and ultimate strength of concretes and mortars, improves mix fluidity, and accelerates concrete hardening. It helps reduce energy consumption during steam curing (TVO/TO) of reinforced concrete and heating of ready-mix concrete.

Purpose:
Used to increase the workability of concrete mixes from P1 to P4 at ambient temperatures down to −5 °C, while ensuring the designed concrete performance.

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:

From 1 L per 100 kg of cement.

Optimal dosage should be determined in the laboratory for each specific technological case.

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.

COMPLEKS K-8

Superplasticizer and accelerator additive with antifreeze effect. It improves concrete mix fluidity, accelerates hardening kinetics, and increases early strength by up to 35% at 1 day and up to 20% at 28 days, compared to similar classified additives.

Purpose:
Used for the preparation of concrete mixes (ready-mix, precast, road) as a superplasticizer with antifreeze effect down to −15 °C.

For precast reinforced concrete: from 0.7 % by weight of binder.
For conventional ready-mix concrete in the cold season (+10 °C and below) with subsequent curing: from 1 % by weight of binder.
For direct freezing of concrete down to −10 °C: from 2 % by weight of binder.

Optimal dosage should be determined in the laboratory for each specific technological case.

Recommendations:

Avoid contact of the additive with the mouth or food products. In case of contact with eyes or skin, rinse thoroughly with water.

COMPLEKS K-11

An admixture for performing concrete works during long transportation to the placement site, at ambient temperatures above +15 °C, in order to preserve the designed strength characteristics of the concrete. It maintains the initial workability of the concrete mix within P5…P4 for up to 4 hours without segregation or loss of plasticity.

Purpose:
Used for the preparation of cement, concrete and mortar mixes as a plasticizer with a retarding effect. Allows work to be carried out at temperatures up to +40 °C with subsequent proper curing of the concrete.
