Basalt Fibre Rebar, Chopped Fibre and Meshes for Concrete Reinforcing
Domeshells is a supplier of basalt fibre reinforcing products
Small quantities are available from the Domeshells shop. For project quantities please contact us.
Basalt Rebar
Available in diameters of 4mm, 6mm, 8mm, 10mm, 12mm, 16mm, 20mm
Available in 100m & 500m coils for 4mm, 6mm, and 8mm diamters
All other sizes available in cut lengths. Please contact us for pricing and shipping.
Basalt fibre reinforcing bar is highly desirable in corrosive environments as it does not rust or corrode. It is one quarter of the weight of steel and that makes it much easier and faster to work with.
Can be cut with an angle grinder or bolt cutters.
Large orders require 3 months lead time
Basalt Chopped Fibre
The chopped fibre is added to concrete and render mixes to add toughness to the concrete and mitigate micro cracking.
Available in length from 4mm up to 50mm
Visit our shop to purchase 7mm fibres in 20kg bags
For larger quantities or different fibre length – Please contact us directly.
Basalt Mesh
Available in various mesh sizes and weights.
5mm square mesh 115gsm – in 100m x 1.0m rolls
10mm square mesh 115gsm – in 100 x 1.0m rolls
25mm square mesh
Visit our shop for 5mm, 10mm and 25mm mesh in 100m x 1m rolls (100m2)
For other mesh sizes and weights please contact us directly
Comparison of Properties – Basalt Fibre v Other Fibres
Why use basalt concrete reinforcing materials
- handling characteristic is easier than steel
- quarter the weight of steel
- speeds construction time
- twice the tensile strength of steel (use one bar size smaller than steel)
- does not rust or corrode (suitable for marine and corrosive environments)
- easy to cut (with bolt cutters of a cut-off wheel)
- does not conduct electricity
- same thermal coefficient as concrete
- it’s a sustainable cost-effective long term solution
What is Basalt Fibre
Basalt fibre is made from a single material, crushed basalt. Basalt of high acidity (over 46% silica content) and low iron content is considered desirable for fibre production. Unlike with other composites, such as glass fibre, no other materials are added during its production. The basalt is simply washed and then melted.
The technology of production of BCF (Basalt Continuous Fibre) is a one-stage process: melting, of basalt and extraction of fibres. Basalt is heated only once. Additional processing of BCF into various materials is carried out using “cold technologies” with low energy costs.
The manufacture of basalt fibre requires the melting of the crushed and washed basalt rock at about 1,500 °C . The molten rock is then extruded through small nozzles to produce continuous filaments of basalt fibre.
They also have a high elastic modulus, resulting in high specific strength—three times that of steel. Thin fibre is usually used for textile applications mainly for the production of woven fabric. Thicker fibre is used in filament winding, for example, for production of CNG cylinders or pipes. The thickest fibre is used for pultrusion, geogrid, unidirectional fabric, multi-axial fabric production and in form of chopped strand for concrete reinforcement.
One of the fastest growing applications for continuous basalt fibre at the moment is the production of basalt rebar that is a substitute for traditional steel rebar for concrete reinforcement.
