Relationships among the chemical, mechanical and geometrical properties of basalt fibers

Abstract

We investigated the chemical, mechanical and geometrical properties of basalt fibers from three different commercial manufacturers and compared the results with those from an industry standard glass fiber. The chemical composition of the fibers was investigated by X-ray fluorescence spectrometry, which showed that basalt and glass fibers have a similar elemental composition, with the main difference being variations in the concentrations of primary elements. A significant correlation between the ceramic content of basalt and its tensile properties was demonstrated, with a primary dependence on the Al2O3 content. Single fiber tensile tests at various lengths and two-way ANOVA revealed that the tensile strength and modulus were highly dependent on fiber length, with a minor dependence on the manufacturer. The results showed that basalt has a higher tensile strength, but a comparable modulus, to E-Glass. Considerable improvements in the quality of manufacturing basalt fibers over a three-year period were demonstrated through geometrical analysis, showing a reduction in the standard deviation of the fiber diameter from 1.33 to 0.61, comparable with that of glass fibers at 0.67. Testing of single basalt fibers with diameters of 13 and 17 µm indicated that the tensile strength and modulus were independent of diameter after an improvement in the consistency of fiber diameter, in line with that of glass fibers.

Parametric optimization and ranking analysis of hybrid epoxy polymer composites based on mechanical, thermo-mechanical and abrasive wear performance

“…The properties and chemical composition of basalt fiber are provided in Table 2. 15,[17][18][19][20][21][22] Marble dust or powder is a metamorphic rock, mainly composed of calcite (a crystalline form of calcium carbonate, CaCO 3 ) and other minerals, such as muscovite, sericite, and chlorite. The properties and chemical composition of marble dust particulates are listed in Table 3.…”

The effect of basalt fiber addition on cement concrete: A review focused on basalt fiber shotcrete

“…A series of relevant standards for basalt fiber and basalt fiber reinforced concrete were formulated in China, such as Shortcut basalt fiber for cement concrete and mortar, Basalt fiber classification and code, Highway engineering basalt fiber and its products (GB/T 23265-2009(GB/T 23265- , 2009Institute of Highway Science, 2010;GB/T 38111-2019GB/T 38111- , 2019. In addition, scholars conducted a lot of research on basalt fiber reinforced concrete, and studied the influence of adding fiber on the early shrinkage, early cracking, impact toughness, compressive strength, flexural and tensile strength, flexural strength and impermeability of concrete (Dong, 2011;He et al, 2012;Sun et al, 2022;Su, 2012;Hemalatha and Ramesh, 2019;Ralph et al, 2019;Alekseev and Kurilko, 2020;Hong et al, 2020;Khan et al, 2021;Li et al, 2022a). However, most studies only focus on a certain aspect of the performance of BFRC, which was not systematic and comprehensive.…”

Viscoelastic Equivalent Creep Behavior and Its Influencing Factors of Basalt Fiber‐Reinforced Asphalt Mixture under Indirect Tensile Condition

“…Basalt fiber (BF) in asphalt mixture has also been compared with some common fiber modifiers [7][8][9][10][11]. For instance, BF has more superior mechanical property and durability than organic fibers and is also more eco-friendly than glass and steel fibers [12][13][14][15][16]. Morova [7] evaluated the influence of BF content on the pavement stability of asphalt mixture by the Marshall stability test, and 0.5% fiber content could significantly enhance the materials stability.…”
