Basalt fiber is a high performance nonmetallic fiber made from basalt rock melted at high temperature, It has great strength characteristics, good thermal resistance and high resistance to an alkaline environment, making it an excellent material for reinforcing concrete. The Basalt reinforced concrete was reviewed for its mechanical properties ...
Aug 01, 2006· In crushed form, basalt also finds use as aggregate in concrete. More recently, continuous fibers extruded from naturally fireresistant basalt have been investigated as a replacement for asbestos fibers, in almost all of its applications. In the last decade, basalt has emerged as a contender in the fiber reinforcement of composites.
The incorporation of basalt and polypropylene fibres in concrete has a major impact on the fracture energy. The major factor influencing this property is the fibre aspect ratio. In practical applications, the combination of these fibres may contribute more effectively to increasing durability than using a .
Up to now, the research on the dynamic compressive mechanical behaviour of basalt–polypropylene fibrereinforced concrete containing mineral admixtures (BPFRC) have, to the best of our knowledge, not been reported. In addition, the lacking dynamic constitutive model for BPFRC is necessary to promote its application in building structures.
The fresh, mechanical, and durability properties of the polypropylene fiberreinforced mortar (PP FRM) and the basalt fiberreinforced mortar (BFRM) with various fiber contents were tested in this paper. The test results show that the presence of polypropylene (PP) fiber and basalt fiber (BF) in the mortar reduces the initial slump flow and increases the slump flow loss rate.
Basalt fiber have better physical and mechanical properties and better alkali resistance, some performance are second only to carbon fiber, and the cost of basalt fiber is far lower than carbon fiber, So the basalt fiber have a broad application prospects in the field of cementbased composite materials.
The objective of this paper is to study the workability, compressive, splitting tensile, flexural, chloride resistance, interface and pore structure of concrete reinforced with polypropylene and basalt fibres. Sixteen mixtures consisting of PP and BF both at volume content of,, and % were fabricated and cured for 28 and 56 days.
In [9], data on the compressive and tensile strengths of fi berreinforced concrete with basalt and polypropylene fibers are presented. The results show that the optimum dose for basalt fiber ...

Basalt Chopped Fibers can be mixed directly into polymers and concrete to increase tensile strength and reduce cracking and chipping.
There has been little research on Polypropylene fibre and none has published on the design method of concrete composition for this fibre reinforcement. Therefore, the research work presented in this paper has been focused onto Polypropylene fibre as reinforcement for concrete.

Basalt Fiber has a similar chemical composition as regular glass fiber but Basalt Fiber has better strength characteristics, and unlike most glass fibers is highly resistant to acidic and salt attack and alkaline, making it a good option for concrete, bridge and shoreline structures.
Matrix basalt reinforcing member constructed and arrange to provide lateral support for the longitudinal bar steel or FRP tendons that provide tensile strength to cementitious material or plastics to reduce bending moment by reducing the onset of shear. The reinforcement members are formed from basalt fibers treated with a thermoplastic thermoset polymer and formed into structures to provide ...

Using BF instead of steel fibre, and in combination of PP forming polypropylenebasalt fibrereinforced concrete (PBFRC) has potential ...
Basalt fiber reinforced polymer rebar is a rod with continuous spiral ribbing, of any length, and with diameter of up to 36 mm. It is produced from basalt reinforced composite materials and offers a combination of high strength and corrosion resistance. Tensile strength of composite rebar is 3 times higher than that of steel rebar.
Basalt fibre has a high content of SiO2, which reacts with the Ca(OH)2 produced by the hydration of Portland cement. As a result, it will form more CSH that is responsible for increasing the general strength of the concrete, Mochamad Solikin [18]. Basalt fibre is a multiperformance fibre. It has several

Based on Experimental investigation for M20 grade of concrete, this paper provides result data of the compressive strength, and split tensile strength of fibrillated polypropylene fiber reinforced concrete (PFRC) containing fibers of 0% and % volume fraction by .
Basalt fiber is a relative newcomer to fiber reinforced polymers (FRPs) and structural composites. It has a similar chemical composition as glass fiber but has better strength characteristics, and unlike most glass fibers is highly resistant to alkaline, acidic and salt attack making it a good candidate for concrete, bridge and shoreline structures.

the addition of steel fibers for concrete have been carried out in the USA by Dinh and others [6] and last time in Canada in the McGill University [7]. However, only very few experimental tests have been conducted on the RC two span beams with nonmetallic fibers, especially with basalt .
In this work, an investigation is made to evaluate the flexural toughness of hybrid fibrereinforced highperformance concrete (HPC) containing different combinations of basalt (B) and polypropylene (P) fibres. The experimental studies consisted of the threepoint flexural tests on notched beam specimens. The specimens incorporated basalt/polypropylene (BP) fibres in 11 mixtures with ...
