Basalt fiber is one of the fibers which can be manufactured from basalt rock. And it is giving properties high modulus of elasticity, interfacial shear strength, satisfactory heat resistance, acceptable chemical resistance, and a less expensive manufacturing procedure when compared to other fibers (Mohammadyan-Yasouj and Ghaderi, 2020). Basalt fiber has been examined for its mechanical qualities and endurance in cementitious composites in the form of a single type, bundled mesh, or composite fibers (Mohammadyan-Yasouj and Ghaderi, 2020).

Basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene and olivine. It is similar to carbon fiber and fiberglass, having better physic/mechanical properties than fiberglass (Table 4), but being significantly cheaper than carbon fiber (Manuele, Bringiotti, Laganà and Fumagalli, 2019). Basalt fibers are 100% natural and inert. Tested and proven to be non-carcinogenic and non-toxic and easy to handle. In contrary, fiberglass is made from a mixture of many materials, some of which are not environmentally friendly. Since basalt is the product of volcanic activity, the fiberization process is more environmentally safe than glass fiber process. Basalt continuous filament is a green product, abundant in nature so it can never deplete the supply of basalt rock. This kind of new product, under investigation and test by Maplad Srl, engineered also by Sogen Srl, could really be the material of the future in the field of the composite materials.

Basalt fibers [68] can be classified as mineral fibers. This new product uses volcanic basalt rock, melted and extruded into fibers. Basalt fibers feature better mechanical properties than glass fibers, and are less costly than the carbon fibers. They display excellent thermal stability, high strength and stiffness, good chemical stability, good corrosion resistance, and good matrix adherence, not being affected by any kind of radiation. They are potentially applicable for thermal protection and structural applications.

There are some key steps to the manufacture of the proposed flexible long-gauge FBG sensor: (1) drawing the optical fiber through the plastic tube and fixing it by bonding the two ends of a piece of fiber sheath; (2) braiding the fiber sheath around the tube and fixing the ends; (3) extending the optical fiber to several hundred micro-strains; and (4) impregnating the fiber sheath with epoxy resin and heating it to solidification. In this paper, the fiber applied is a basalt fiber, selected on account of its larger ultimate strain, lower cost than carbon fiber and better durability than glass fiber. The specimen of the proposed sensor is presented in Figure 3. The configuration indicates that the sensor can be easily curved for attachment to the curved surface of a shield tunnel.

Although steel fibres, polypropylene fibres, and glass fibres have been studied as reinforcements in cement concrete, they have different disadvantages that limit their application in cold areas. For example, polypropylene fibres have low tensile strength and elastic modulus, and pollutants are discharged during the production process of glass fibres; the extensive use of deicing salts in cold areas accelerates the corrosion of steel fibre (Ferella et al. 2019, Pakravan and Ozbakkaloglu 2019, Wu et al. 2020, Ahmed and Lim 2021). Basalt fibre is a natural mineral fibre with excellent mechanical strength and corrosion resistance, and it involves a green and pollution-free synthetic method (Chen et al. 2020, Patti et al. 2021). The elastic modulus of the basalt fibre is similar to that of an aggregate, which can avoid the non-synchronized deformation under fatigue load owing to the modulus difference and disperse the frost heaving force in freeze–thaw cycles to significantly improve the fatigue performance and frost resistance of concrete (John and Dharmar 2012, Khan et al. 2020, Saradar et al. 2020). Thus, compared with other fibres, the basalt fibre has the advantages of environment-friendliness, high strength, and synergistic deformation, which is more suitable for application in cold areas.

Another famous reinforcement for fabricating hybrid composites is E-glass. It has high electrical resistance and modulus. It was also found that glass fibres exhibit better tensile and compressive strength and offers great resistance to chemical, heat, moisture and fatigue properties. Glass fibres have low impact strength, low strength to weight ratio and high density compared to other synthetic fibres; therefore, glass fibres are often combined with Kevlar fibres or carbon fibres (Gokuldass and Ramesh 2019). Presently, basalt fibre gained special attention as a replacement of glass and carbon fibre due to its increased physical, chemical and thermal properties. Basalt fibres are also used as temporary patches in the repair of carbon fibres. From literature, it was found that Kevlar hybrid with E-glass composites have high impact strength than basalt hybrid with E-glass composite laminates; this effect is because the interfacial bonding between Kevlar and E-glass is remarkably high (Jain, Singh, and Shrivastava 2019b). However, moisture can degrade the strength of the glass fibre, plasticise, swell or micro-crack the resin and degrade the fibre/matrix interface by either chemical or mechanical attack (Guermazi et al. 2014).
