Study of "Saralsk" Deposit for Practical Applications in Construction

In article the results of research structural features and technical properties andesite - basalt stone rock “Saralsk” deposit are given. The material is estimated by its mineral petrographic composition, cuts/refinements materials have been made for microscopic study mineral-petrographic composition. Researches conducted according to requirements acting standards as a result, it became clear, that consists basically minerals opacitized hornblende plagioclase, doesn't contain any no secondary such hydroxides iron, chlorites, epidote, quartz, saricite, etc. Petrographic researches allowed determine species rock. density, strength, water resistance frost studied. suitability practical application in construction, including external works, revealed.
