Аннотация: In this work, the aim was to define the dependence of the strength ofbasalt fibers (BCF) on their chemical composition, characterized by two parameters: the NBO/T ratio and the acidity modulus Ma. It makes it possible to predict thechange in the mechanical parameters of fibers from their composition, since basaltrocks have a significant drawback - the inconstancy of the chemical composition.Fibers of various chemical compositions were obtained based on 14 differentbasalt deposits. Pearson’s correlation coefficient for NBO/T and ultimate tensile strength was 0.79, and for acidity modulus and tensile strength it was 0.53.The tensile strength of tested fibers from different deposits ranges from 1495 to3380 MPa.In addition, with the help of the Raman spectra analysis, it was confirmedthat tensile strength can be largely determined by the influence of the chemicalcomposition of basalts on their structure.
