Research of the Effect of an Extreme Cold Climate on the Properties of Basalt Plastic Rods

Abstract

This article presents the results of studies of the infl uence of an extremely cold climate on the physicomechanical properties of basalt plastic rods of a periodic profi le. Changes in mechanical parameters were determined for the initial and exposed samples of basalt plastic reinforcement. After exposure in Yakutsk, an increase in strength properties by 4-12% was found, depending on the diameter of the rods. The results of thermophysical studies allow us to justify the high stability of the BPA in terms of thermal expansion.
