【 摘 要 】

The limited choice of construction materials under the extreme conditions of the Russian Arctic and the necessity to solve the ecological problems after the intense development of territories in the USSR raise the issue of utilizing the unnecessary dwelling and industrial buildings and using the obtained wastes. The most widespread material is reinforced concrete. The authors propose using concrete with angular aggregate made of crushed concrete. Based on the properties analysis and the technology of producing and processing both materials, the authors regard the possibility and area of their application. The aim of the research was to prove the possibility of using the construction materials based on utilization of the secondary raw materials - crushed reinforced concrete - under the extreme conditions of the Russian Arctic and to define the spheres of application. The main method was comparing the experience of using crushed concrete on the continent and in the Arctic. The possibility is studied to use the crushed concrete for low-burden foundations and basements, and as coarse aggregate for concrete when erecting buildings, constructions, and motor roads in the Russian Arctic. The crushed concrete and the concrete with aggregate made of crushed concrete can be used in the Russian Arctic provided certain conditions are observed related to the volume of the crushed concrete in the mix and the maturing of concrete under positive temperatures till the critical strength is achieved.
