Fragmentation conclusion It is known, that from point of view of cancer hazard the lengthdiameter ratio R is very important. For basalt fiber fragments is ratio R 230.5111.08 20.8. Despite of fact that basalt particle are too thick to be respirable the handling of basalt fibers must be carried out with care.
Basalt fibers b asalt fiber is similar to carbon fiber and fiberglass, but basalt has better mechanical properties than fiberglass and is lower in cost than carbon fiber. it is used as a fireproof textile in the aerospace and automotive industries and can also be used as a composite to produce a wide range of products features 1.

Basalt fiber is known as green industrial material. basalt fiber is colloquially known as the 21st-century nonpolluting green material. basalt is a natural material that is found in volcanic rocks originated from frozen lava, with a melting temperature comprised between 1500c and 1700c.7,8 basalt fibers are 100 natural and inert.
Strength basalt, high-strength and high-modulus carbon fibers were used, that is to say, the production of composites, reinforced by hybrid fibers hfrc was organized 3-8. here we dont detail the properties of these and other types of reinforcing fibers.
The fire spalling resistance of basalt fibre concrete was assessed through a series of pilot experiments. the fire test results show that macro basalt fibres do not improve the fire spalling resistance of high-performance concrete. however, the use of basalt fibres does
Basalt, basalt rock, basalt fiber, basalt fiber bar, basalt fiber rod, fiber reinforced polymer introduction the need for non-corrosive reinforcement of the construction industry has developed in the last decades. there have been several researches and tests of integrating basalt fibers into concrete structures, mainly concrete beams.

Basalt rebar reinforcement is an alternative to steel and fiberglass for reinforcing concrete. made from volcanic rock, basalt rebar is tougher and stronger than steel with a higher tensile strength. much lighter than steel, 89 percent in fact one man can easily lift a 100 meter 328 foot coil of 10 mm basalt rebar.
The model of the fiber, which was produced by the shanghai russian basalt fiber co. ltd., differed from that investigated by wang et al. the tow was prepared by dipping in 648 gum epoxy. the results figure 1a showed that the mass of the fiber decreased slowly with increasing alkaline corrosion time after soaking in an alkali solution.
Flax fiberreinforced polymer composites were determined to be effective in confinement of concrete cylinders. flax fibers exhibit strong intrinsic hydrophilic properties and relatively inferior mechanical properties therefore, combining them with mineral-based natural fiber i.e. basalt fibers was proposed.
