Physico mechanical characteristics of basalt melt

Research relevance: knowledge of mechanical characteristics of petrified products allows to use them most effectively in various industries. In specific application of stone casting, all technical, physical and chemical properties are required at the same time. Research objectives: determination of physical and mechanical properties of basalt in assessment of ability of glass-ceramic casting and resistance to external influence of any factor. Research materials and methods: stone casting, compared with metal, glass, plastic, concrete, has increased chemical resistance to aggressive environments and high resistance to mechanical abrasion, has good dielectric properties, low water absorption and high hardness. These properties depend on the chemical, mineralogical composition, the structure of the casting and the degree of crystallization. Research results: the porphyry structure negatively affects the strength of product. Conclusions: the decrease in temperature in absolute value does not exceed the value of thermal resistance at 900°С equal to 210°С, therefore, the product does not break. Low heat resistance, increased brittleness, poor resistance to impact loads, low bending and tensile strength imposes special conditions on the products exploitation.
