MATEC Web of Conferences, 2017
Basalt is a material available in big quantities in nature. It has a low price and can be used in various domains. It can be relatively easily extracted from natural deposits and processed by means of melting. Melted and recrystallized basalt has demonstrated promising behavior with regards of its use in manufacturing, as reported in the literature. This work aims to present some aspects regarding the opportunity of using basalt in manufacturing the subassemblies of machine-tools. The research was made using grey cast iron and steel parts as reference for a comparative study. The researches presented in this work were focused on analyzing the behavior of basalt parts submitted to static stress. Testing methodology, specific measuring apparatus used, experimental test data records, data processing and resulting conclusions are presented in the paper.
Experimental Investigation on Mechanical Properties of Basalt-Core Reinforced Materials
IRJET, 2022
A composite material is a combination of two or more different materials; it gives superior quantity than its constituents. Composite materials not only used for structural applications but also in various other applications such as automobile, aerospace, marine, etc. This work describes an experimental mechanical characterization campaign on composite made out of unidirectional Basalt raw with 8 layers. The strength of the material is observed by performing mechanical tests. A core material is introduced in combination with basalt to check the mechanical properties of raw basalt with core as ingredient. In addition to that the influence of core on the strength and thickness of the material is also evaluated by knowing the percentage improvements in strength were the cost of the material also reduces due to the addition of core material. The work has used raw materials from commercial catalogues with no further modification. Compression mould is the manufacturing method used to prepare the sample. After mould process the sample is tailored to ASTM standards for testing
Analysis of the eigenfrequencies of the basalt machine parts by the FEM
MATEC Web of Conferences, 2021
The aim of this paper was to carry out a theoretical (numerical) scientific research on the behavior of cast and recrystallized basalt, in order to use it as a material in the manufacture of structural elements of machine tools. A unitary methodology has been established for studying the eigenfrequency of structural elements for machine tools by the finite element method. Two basalt structural elements (beam type and plate type) were modeled, which were also made physically, and with the help of the COSMOS / Mark finite element program, the eigenfrequencies of the models was studied.
New correlations between uniaxial compressive strength and point load strength of basalt
International Journal of Geotechnical Engineering, 2014
Although the mechanical and physical properties of many rocks have extensively been studied, little work is reported on basalt rock. This paper discusses the interrelationships between the mechanical and the physical properties of the basalt rock. Laboratory tests were conducted on rock cores collected from over 22 locations within the Mumbai city limits. The samples were tested in accordance with ISRM (1985) specifications. Correlations between the uniaxial compressive strength (UCS) and the point load strength index (I s.50) were developed. It was observed that other than the customary linear relations and power function between UCS and I s.50 , a bilinear relation best fitted the laboratory data.

Basalt fiber having properties such as low density, low cost, and environmentally safe and chopped strand is a synthetic fiber having properties such as electrical and fire insulation, moisture resistance, corrosion resistance etc.,
Mechanical Characterization of Compact Basalt by using SHPB Device
Proceedings, 2018
In the present work, dynamic stress-strain response of compact basalt is tested under high loading rates using 38 mm split Hopkinson pressure bar (SHPB) device. The physical and static mechanical properties of compact basalt, e.g., density, specific gravity, static compressive strength and elastic modulus values are also determined. Petrological studies of compact basalt are carried out through X-ray diffraction (XRD) test and scanning electron microscope (SEM) test. In the SHPB tests, it is observed from the stress-strain response that the dynamic peak stress increases with increasing strain rate however the elastic modulus is nearly constant with increase in strain rate. Dynamic force equilibrium at the incident and transmission bar ends of the rock samples is attained in all tests till the failure of the rock samples. Dynamic increase factor (DIF) for the rock is determined at a particular strain rate by comparing the dynamic to static peak compressive stress. Correlation equation for dynamic strength increase factor with respect to strain rate has been proposed herein.

Open Journal of Civil Engineering, 2022
Due to the mass demand for excellent construction materials for infrared and super structures in Jordan, intensive field and laboratory works were carried out to determine the quality of basalt as a source for construction uses or as aggregate materials. Representative basaltic samples were collected from four quarries in Harrat Ash Shaam Basalt (HASB), northeast Jordan (Al-Azraq, Tel-Hassan, Q'a-Khanna and Al-Aritayin). Necessary and accentual quality control tests were carried out on 17 samples of basalt to determine the physical and mechanical properties of target samples, whereas petrographic and chemical analysis for some representative samples have been carried out using a polarizing microscope and X-ray fluorescence (XRF). This study aims to focus on the main engineering characteristics of the basalt rocks and to shed some light on their properties. This work represents the results of petrographic and chemical analysis, tests of abrasion, absorption, specific gravity, unit weight and void ratio, sieve analysis (gradation), soundness, flakiness and elongation indices, pulse velocity and compressive strength. Petrographic studies show that the basalt is characterized by a presence mainly of calcicplagioclase feldspar, pyroxene-augite and olivine. The composition of the basaltic samples reflects ultrabasic-basic (Basanite-Tholeiitic basalt type). The basalt is characterized by higher specific gravity, lower absorption and medium abrasion loss values, and resistance to corrosion, with medium to high compressive strength. The results of the studied physical and mechanical properties of the basalt that have been tested comply with the standard requirements. In most of the studies, basalt has good physical and mechanical properties that can be used for engineering applications.

This article presents research on the possibilities of creating value-added unconventional materials, functional fabrics and products from local basalt and basalt roving. Basalt fiber, i.e. roving, is used to make knitwear and heat-insulating cord. The thermal insulation cord was tested in the "SNOL 15/1200" electric furnace in the laboratory of the "Mega invest industrial" LLC joint enterprise and its durability up to +980ºС was determined.
