Basalt Rebar

Description and basalt rebar range. Price upon request

Basalt rebar is a rod with continuous spiral ribbing, formed by winding it with a basalt yarn moistened with a high-strength polymer compound. It is a promising composite material with a wide range of applications in construction.

Basalt rebar is resistant to corrosion and aggressive chemical compounds, is unusually light and durable. The research results showed that the durability of building structures with basalt reinforcement significantly exceeds the service life of similar structures made of other materials.

Basalt rebar is a composite material of the future, which has its supporters in many countries of the world and, according to forecasts, will soon occupy a permanent niche in the construction industry. And although the concept of “composite material” is not new for specialists, mankind has continued to use metal for a long time.

What is a composite rebar?

Composite rebar is a non-metallic rod made from glass, basalt, carbon (carbon) and aramid fibers with polymer compounds. At a time when glass rebar has been in the market for a long time, basalt rebar is a relatively new product that is actively gaining public confidence and is increasingly used in various projects every year.

Basalt rebar is manufactured using continuous basalt roving. Externally, it is a rod with continuous spiral ribbing formed by winding with a basalt braid moistened with a high-strength polymer compound.

Since 2004, Technobasalt Invest has been one of the world leaders in the production of continuous basalt fiber, and since 2009 in the production of basalt rebar. Basalt rebar under the Technobasalt® trademark has the ANPB marking (non-metallic basalt periodic profile rebar) and complies with the normative document DSTU B V.2.7-312: 2016. Technobasalt Invest is a manufacturer that values ​​its reputation; all products are manufactured in accordance with technical specifications, registered in the Ukrainian Ministry of Regional Development. Our products are certified by UkrSEPRO. The company applies a management system in accordance with ISO 9001: 2015.

To better understand the product, you need to know how it is produced, so let’s briefly dwell on the technology for the basalt rebar production. It can be divided into the following main stages:

  • installation of basalt roving bobbins on the creel;
  • impregnation of roving with binder components;
  • formation of a periodic profile on the winding unit;
  • rebar cooling;
  • cutting the length of bars at the rebar cutting unit;
  • rebar packing into bundles, marking.

The state enterprise “State Research Institute of Building Structures” tested samples of basalt rebar produced by Technobasalt-Invest, LLC for tensile strength. As a result of rebar Ø10 mm testing, a tensile strength of 1405.3 MPA was obtained, which is 4 times higher than the tensile strength of steel reinforcement.

The results of studies of concrete grades  B25 and B30 and cement mortar M100 with the addition of Technobasalt TM basalt fiber showed that the tensile strength in bending increases up to 30% in the concrete grades B25 and B30 and by 48% in the M100 cement mortar. Compressive strength increases up to 14% in concrete grades B25 and B30 and by 58% in cement mortar M100.

The basalt rebar is an effective reinforcement system

Improves the strength characteristics of concrete products:

  • low specific gravity: 4 times lighter than steel rebar;

  • does not corrode, does not rot, does not warp;

  • high chemical resistance to aggressive media;

  • low thermal conductivity;

  • dielectricity;

  • wide operating temperature range from -70 to +160 °С;

  • the coefficient of thermal expansion is closest to concrete thermal expansion coefficient.

Has a direct economic effect:

  • reduces labor costs for reinforcement work and the rebar price itself due to a possible increase in the size of the reinforcement mesh cell and a decrease in the diameter of the reinforcement;

  • the ability to carry out assembly and loading and unloading operations without using special lifting mechanisms and equipment;

  • reduces transportation costs due to the lower weight of basalt reinforcement.

    Provides long-term economic benefits:

    • increases the reliability and durability of structures;
    • as a result, it reduces operating costs, increases the turnaround time.

    Basalt reinforcement performs perfectly reinforcing functions, especially with basalt fiber, added as a reinforcing additive to concrete.

    Basalt rebar Technobasalt® is manufactured in full compliance with TU U V.2.7-26.8-34323267-002: 2009.

    The company applies a management system in accordance with ISO 9001: 2015.

    We have made tests for the basalt rebar (ANPB) adhesion to concrete: the research results showed that the general form of the curves of the tangential stress-shear strain for ANPB corresponds to similar curves for steel reinforcement, and the obtained values ​​of shear stresses for 8 mm, 10 mm, 12 mm meet the requirements of EN 1992-1-1.

    It was also proved that the parameters of ANPB adhesion to concrete  are close to the corresponding parameters of type A rebar, and it is possible to use the calculated dependencies for steel reinforcement of periodic profile for ANPB (B) anchoring calculating in concrete.

    We have also tested ANPB samples to determine the ultimate tensile strength. The tested sample of ANPB 10 mm collapsed along the main rod under the metal tube, and temporary resistance to the break of ANPB 10 mm was 1405,5 MPA.

    Basalt rebar tests for fatigue strength showed that the fatigue limit based on 2 × 106 cycles tests varies from 31.5 to 33.0 kgf/mm2 (315 to 330 MPA) with a 1080 MPA static strength of basalt rebar, which corresponds to the strength limit of high-strength A-1000 steel reinforcement. At the same time, the relative elongation of basalt reinforcement is in the range of 1.9 to 2.2%, which is commensurate with the elongation of A-1000 reinforcement.


    Basalt rebar:
    uncopyable competitive advantages

    We believe that basalt rebar has significant advantages over steel and fiberglass rebar in a wide range of applications. Go to the page using the link, and you will find out why we think so …

    The basalt rebar is a very durable reinforcing material

    • Basalt rebar is 3 times stronger than steel rebar (the strength of basalt reinforcement is about 800–1100 MPA, while steel reinforcement has a strength of 225-365 MPA).

    • Coefficient of basalt rebar thermal expansion is very close to concrete: α basalt = 0.0000065 and α concrete = 0.00001.

    The basalt rebar is a very lightweight reinforcing material

    • Basalt rebar is 4 times lighter than steel rebar (valid for the same diameters) and 7-9 times lighter with equal strength replacement.

    • Transportation costs are minimized.

    The basalt rebar is easy to install

    • Basalt rebar does not require on-site welding and is knitted with ordinary knitting wire or plastic ties.

    • Basalt rebar does not require special lifting mechanisms and equipment.

    The basalt rebar is unique in its properties

    • Basalt rebar helps to increase the durability of cement-concrete structures.

    • It has high corrosion resistance.

    • Has low thermal conductivity, diamagnetic, dielectric.

    Today, the most popular areas for the use of basalt rebar are the road industry, civil and industrial construction, special structures that work in an aggressive environment, architectural cement concrete products. There are spheres where it is impossible to work without this innovative material, namely: the construction and repair of water treatment facilities, storage facilities, processing and disposal of household solid and liquid waste products of settlements, reinforcement of concrete structures operated in conditions of high voltage electromagnetic fields and potential differences (NMR tomography boxes, supporting structures of high-voltage lines and substations, etc.), construction of bridges, hydraulic structures, strengthening of coastlines, reconstruction of structures that are constantly exposed to water or other aggressive factors, etc.

    In a result of steel reinforced projects recalculation for alternative reinforcing materials a positive economic effect is achieved, besides using of basalt reinforcement and / or basalt fiber provide a noticeable increase in quality characteristics. The use of basalt rebar helps to minimize the transportation cost, handling and repair works cost , and does not require an additional protective layer of concrete, since basalt rebar does not corrode.

    If you want to qualitatively differ from your competitors, then we suggest considering basalt reinforcing materials as an innovation in the development of your technologies.
