Abstract

This paper presents the data of changes in the coefficient of thermal expansion of composite reinforcement and heavy concrete in a wide temperature range. Studies allow not only to justify the high stability of the BPA in terms of thermal expansion, but also to assess the subtle effects of measured parameters for parallel samples in the initial state and after climatic tests in Yakutsk. We identified the optimum relations of heavy concrete with limestone rubble of 60 % and gabbro-dolerite - 40 %, providing high degree of compatibility of temperature expansion with composite armature, for increase of crack resistance and excluding crack formation at temperature changes. The results allow to determine the optimal formulation of concrete reinforced with composite reinforcement for their possible use in the creation of new structural materials.
