Quality Evaluation of the Kuluevskaya Basalt Outcrop for the Production of Mineral Fiber, Southern Urals, Russia

Abstract

More recently, a significant growth is observed in the manufacture of composite materials. Intensively developed polymer composite materials (PCM) are used in different sectors of industry and technology. They are successfully replacing traditional construction materials and also permit the conditions that exclude use of metals. Basalt fiber is one of these materials, it have caught come into the spotlight due to their superior physical and chemical properties in which they only rank below expensive carbon and silicon carbide fibers. The suitability of raw material for basalt fiber production is mainly determined by the mineral composition and crystallization properties of basalt melts. In this article, we present the results of an integrated petrographic and mineralogical investigation of melanocratic basalts of the Kuluevskaya volcanic complex from the Southern Urals, in order to assess their suitability for the production of high quality basalt fiber. The low acidity and viscosity parameters indicate the possibility of producing brittle fibers with a poor chemical resistance. Moreover the redox state and content of iron in the basalt glasses determine high crystallization ability of basalt fibers, it limits their application temperature and leads to low productivity of the BCF production process, but keeping acceptable insulation properties, hence their significance in the construction industry is high.

Physical and Mechanical Properties of Composites Made with Aluminous Cement and Basalt Fibers Developed for High Temperature Application

“…Basalt is consisting of number of oxides with essential impact on its final properties. Dominant SiO 2 is represented by 43.3-47.0% of weight, content of Al 2 O 3 is just about 11.0-13.0%, CaO and MgO are both represented in case of basalts of common chemical composition by 8.0-12.0%, and other oxides form just up to 5% of weight [12,13]. Chemical properties, especially content of SiO 2 , influence the possibility of processing to fibers.…”

Utilization of Some Egyptian Raw Materials in Rock Wool Industry: Thermal and Acoustic Insulation

“…In addition, the higher MgO content would initiate its separation form the melt as crystalline olivine which would minimize the wool quality. As well, iron and titanium would motivate the melt crystallization (Lebedeva, 2007 andPerevozchikova et al, 2014). The average CaO/MgO ratio recorded 0.96, 1.51 and 1.69 in Baharyia, Abu-Zaabal and El-Fayoum respectively.…”

“…All the collected basalt samples exhibit basic composition with CaO/MgO ratio ≥ 0.5, proving their suitability for the wool industry applying either the one component scheme, i.e., the duplex method (Lebedeva., 2007) or the two-component scheme, i.e., the Cupola technology, as well (STM ® , 2010& Perevozchikova et al 2014. When the CaO/MgO ratio is ≤ 0.5, i.e., increase of MgO, the basalt rocks are not suitable for the wool production due to the higher melting temperature required for the industrial operation.…”

“…The short fibres are those known as rock wool or basalt wool and mainly used in the formulation of insulation boards and blankets. The continuous fibres are characterized with higher tensile strength over the short ones allowing their use in the composites and reinforcement applications (Perevozchikova et al 2014;Jamshaid andMishra, 2015 andElbakian et al, 2018).…”

“…Pyroxenes are a group of crystalline silicates that contain any two of three metallic oxides, magnesium, iron or calcium. Olivine is a silicate that combines magnesium and iron (Mg,Fe)2SiO4 [10].…”
