The ORLIMEX CZ Company obtained the first ever construction-technical certificate in the Czech Republic for the sale of «Composite materials from basalt fibres»!
The company ORLIMEX CZ, s.r.o. in 2016 expanded its business activities in the construction industry. There is a new field of composite materials — as a substitute for traditional steel reinforcement.
It offers two types of composite materials to its business partners. These are basalt fibre materials (internationally labeled BFRP) and fibreglass fibre (labeled GFRP) — these materials are an adequate replacement for the reinforcement in the concrete construction instead of steel.
ORLIMEX CZ, s.r.o. is an exclusive representative of the Russian company GALEN designated for the Czech Republic, Slovakia and Poland. GALEN is a world producer of composite materials and one of the first producers of composite basalt materials and glass fiber materials, not only in Russia but also in Western Europe.
Basalt is a rock of volcanic origin and it forms about 30% of the Earth’s crust. It is an extremely durable and hard material of a fine-grained structure. It is resistant to abrasion and chemicals.
Thanks to these properties, basalt began to be used to produce modern composite materials.
Main advantages of basalt:
- high tensile strength — basalt fibre is getting closer to carbon fibre strength (basalt is 3 times stronger than steel, but 4 times lighter)
- thermal conductivity — the basalt has a low thermal conductivity (100 times smaller than steel), its use allows to increase the thermal efficiency of building walls by up to 35%
- anticorrosion properties
- electric conductivity
- resistance in alkaline and chemical environments
- cohesion with concrete — bars covered with silica sand
Basalt and composites
Composite is any material that consists of at least two major components with markedly different physical properties. It is made from fiber reinforcement and composite binder. The most common is a composite of organic polymer resin and basalt or fiberglass fibers
PULTRUSION — Production technology
The English name «PULTRUSION» is a process of continuous production of reinforcement of various shapes and lengths by drawing. The inlet material is a mixture of liquid resin and fiber reinforcement. The process involves pulling the material through a heated steel mold, sometimes filled with silica sand due to good cohesion with the concrete and dividing it to the desired length.
