Purpose

High-range water reducing, superplasticizing additive "Superplasticizer SK 1" TM MTC Concrete — a high-range water-reducing superplasticizer used in the production of reinforced concrete products (RCP) and ready-mix concrete. Suitable for use at temperatures from 5 °C to 35 °C.

Superplasticizer SK 1 TM MTC Concrete is used for:

  • production of ready-mix concrete and RCP, including prestressed concrete;

  • concretes of consistency classes from R2 to R5;

  • ready-mix concrete with extended slump retention;

  • pumpable concrete via concrete pumps;

  • high-strength and self-consolidating concrete (SCC).

The SK 1 superplasticizer MTC Concrete — is also used to improve the appearance and physico-mechanical properties, especially of products requiring high-quality surfaces.

Properties

Additive SK 1 has strong plasticizing properties that allow reduced water demand and increased density and strength of concrete.

SK 1 TM MTC Concrete ensures:

  • enhanced flowability and workability of concrete mixes without segregation;

  • energy savings during fresh concrete processing;

  • significantly improved early and final compressive and flexural strengths of concrete products;

  • increased frost-thaw resistance and de-icing salt durability;

  • smooth, uniform concrete surfaces;

  • up to 20–30 % cement savings compared to non‑additive mixes.

Dosage

Recommended dosage: 0.2 – 1.2 % by cement mass.

Optimal dosage depends on required concrete performance and is determined experimentally.

Application

Add SK 1 superplasticizer TM MTC Concrete into the pre-mixed concrete mix or with mixing water. Important! Do not add to dry concrete mix!

Frequently asked questions
What raw materials are used in the production of this product?

Long before launching our own production in 2007, the MTC Concrete team began a thorough search for the highest quality raw material suppliers. Thanks to the extensive experience of our in-house R&D centre, we have established reliable and lasting partnerships with top-tier producers—both in Ukraine and across the EU—recognised as industry leaders.

Direct sourcing from raw material manufacturers ensures the consistent quality of MTC Concrete products, while long-term collaboration allows us to confidently refer to these companies not merely as suppliers, but as true Partners.

Where can I see customer reviews about this product?

In the B2B and B2G market segments, customer reviews are rarely published, as the dissemination of information about the approaches and results of using specific admixtures often constitutes a commercial secret.

We believe that the best testimonial for a product is a successfully implemented project where the product was used. Reports on such projects are published after completion, subject to agreement with our partners. You can find all available reports in the “Information” section, or directly under the product if there is already an applicable experience that can be shared.

Does this product have all the necessary certificates?

In accordance with the Law of Ukraine "On the Provision of Construction Products on the Market" (effective from 1 January 2023) and Order No. 594 of the Ministry of Regional Development, dated 27 March 2025, which approves the current List of National Standards including DSTU EN 934-2:2019, a certificate of conformity is no longer a mandatory document for concrete admixtures.

Instead, manufacturers are required to provide a Declaration of Performance (DoP) and apply CE marking (Conformité Européenne). The CE mark confirms that the product complies with European standards for safety and quality.

Consequently, to place concrete admixtures on the Ukrainian market, adherence to European norms and standards is necessary, rather than the previous mandatory certification requirements.

The manufacturing plant where this product is manufactured meets the requirements of the international standard ISO 9OO1:2O15 "Quality management systems. Requirements" (DSTU ISO 9001:2015 "Quality management systems. Requirements", IDT).

Is it possible to get a free consultation on this product?

Of course, you can get a free preliminary consultation either at the office of the "Koalida" company or fill out a request via the form on the Contacts page. You can also get advice from a technical specialist by calling the phone number: 077-500-11-00.

In our product range you will find solutions for almost any type of concrete mixtures and mortars that meet all quality and reliability requirements.
