Basalt rebar is easily cut to length with regular tools. Basalt rebar does not conduct electricity or induce fields when exposed to RF energy, great for MRI or data buildings. On average 60% less CO2 emission in final concrete structures due to production process, logistics and material optimization. Overall project cost is less than with steel ...
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 rocks, however, do not require this but contain a natural nucleating agent (nucleates at high temperature) such as Fe 3 O 4 during the melting process, hence giving advantages over the other fibers, where nucleating agents are necessary to obtain a similar microstructure (Yilmaz et al., 1996).

Mar 01, 2017 Various manufacturers have employed this fibre because of its low cost, high ecological compatibility during the production process, and functional properties [8-11]. The density of basalt (2600 kg/m3) is approximately one third of the density of steel (7680 kg/m3), which means BFRP is a lighter, stronger construction material compared to steel.
Jun 22, 2016 Basalt does not rust or corrode resulting in a much longer lifespan compared to steel. No regulation states that steel has to be used exclusively – adding basalt reinforcements is a solution that is available now and in total saves money, bottom line! The Problem with Reinforced Concrete
ORLIMEX have obtained the first ever construction-technical certificate for the sale of composite materials from basalt fibres. ORLIMEX UK Ltd in 2016 exp anded its business activities in the construction industry and formed a new division Orlitech to supply composite or FRP (Fibre Reinforced Polymer) materials in the UK – as a substitute for traditional steel reinforcement.

Finally, the basalt exits the assembly as continuous, glass-state fibers, We take thousands of continuous strands of Basalt fiber which are compressed until they form a cylinder-type shape. During this process, they are coated with our proprietary epoxy resin, which acts like adhesive to give the basalt rebar an enhanced bonding surface.
A process of submerged nozzle continuous casting wherein there is used, as a flux layer on the upper surface of the molten metal in the casting mould, a flux composition including the mineral basalt.
The process of basalt casting starts with discerning quarrying of the rock. It is then melted at 1280 C and then casted in the form of moulds and cylinders. The basalt castings that are produced are then exposed to a cycle of heat treatment. They are placed in kilns for the production of basalt in a re-crystallized form.
Basalt roving is a basic raw material for production of various reinforcing and heat-insulating materials. Rowing is a non-twisted continuous thread, which consists of fibers of small diameter (9/13/16 μm) and linear density that ranges from 330 to 4800 tex.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
Feb 06, 2018 The results show the different character of the load-deflection relationship of basalt reinforced beams compared to traditionally steel reinforced beams, as well as the significant influence of the type and quality of anchoring on the process of basalt bars tensile process.
440c stainless steel is martensitic, which implies that it is hardenable by heat treatment. The general goal of the heat treatment of 440c stainless steel is to limit, as much as possible, the amount of austenite in the steel and promote the creation of martensite . Heat treatment of 440c steel typically proceeds as follows: 1. Full annealing
Apr 13, 2016 Basalt is one of the most common rocks on the planet, and is the only ingredient needed to make basalt fiber. In terms of corrosion or degradation there is almost nothing that affects it.
Apr 23, 2019 If basalt fiber providers can point to one application that portends particularly well for BFRP growth, it would be rebar. Like fiberglass rebar, basalt rebar is considerably lighter than conventional steel rebar, “over 70 percent lighter, in fact,” Gencarelle says. “One person can easily lift a 100-meter coil of 10-millimeter basalt ...

A process for obtaining a resulfurized fine-austenitic-grain steel, of the type of carbon steel and alloy steel, produced by continuous casting and suitable for casehardening and hardening-tempering treatments, said steel containing S in amounts equal to or higher than 0.02% by weight, in which said process comprises a first addition of Mn to said steel in amounts equal to or higher than 8 ...
Aug 29, 2014 • High strength Specific strength of basalt fiber is 2.5 times higher than the strength of alloy steel and 1.5 times higher than the strength of fiberglass. • High thermal stability BF can be used for a long term within temperature range from -200 C to + 600 C.
Oct 05, 2019 Basalt rock fibres have new range of material in building construction, road construction, concrete industry and agriculture field. The basalt fibre rebar having full resistance against corrosion may be good alternative for the reinforcement of concrete structures, like RC bridge girders subjected to an environmental attack.
Jun 21, 2018 Having decided that basalt fiber is the best compromise between efficiency and sustainability, the company patented the technology to obtain out of autoclave Fiber Metal Laminate, a composite material made of thin layers of aluminum and fiber consolidated by a vacuum assisted infusion process.
2. TECHNOLOGIES FOR OBTAINING PARTS FROM MOLDED AND SINTERED BASALT Obtaining finished basalt products raises a number of special issues in terms of processing technology and in establishing processing technologies.

First the basalt is brought back to lava by heating it till 1500 0 C and by applying a very rapid solidify process hereby the normal crystallization process is disrupted and the basaltfiber becomes an amorphous material with outstanding properties. Such as 2,5 times stronger than steel , 4 times lighter than steel , the CO2-footprint is 170% lower in comparison with the production of steel and ...
Basalt fibre is made by chopping continuous basalt fiblre into short lengths. Basalt fibre used as reinforcing agent for concrete, plaster and plastics, providing three-dimensional strengthening. To achiene better adhesion, uniform distributiona nd maximum reinforcing effect, depending on application area, it is necessary to selecta relevant monofilament diameter, cut length, moisture content, and sizing.
Dec 11, 2020 The main reason for this finding is because the basalt fibers play a small role in the compression process, and the basalt fibers along the length of the specimen are evenly distributed between the steel fibers in the bending test and play a bridging role with the steel fibers throughout the bending process.
Oct 01, 2020 The basalt rebar is made of epoxy and prestressed basalt yarn and the basalt yarn is made from the basalt fibre string. The 10.6 μm basalt fibre string specimen has been experimentally tested to obtain its tensile strength in literature [ 33 ].
