ELECTROCONDUCTIVE CEMENT CONCRETE COMPOSITE DEVELOPMENT AND ITS APPLICATION IN THE ROAD INDUSTRY

Abstract

This article discusses electroconductive cement concrete characteristics and suggests methods for using this material in the "warm roads" construction. It is proposed to use the heated pavement for snow and ice accelerated utilization during roads and streets winter maintenance. Recommended technology will help reduce the most expensive winter cleaning operations cost - loading, transporting and melting of snow mass. The authors experimentally selected stable electroconductive concrete mixtures with different conductor component contents. To prove the possibility of using electroconductive cement concrete as a road-building material the strength of samples was determined. Developed cement concrete composition variants with carbon addition, the results of compression and tensile tests and study of concrete electrical conductivity and the ability of this material to heat up are described.
