FORMULATIONS OF ELECTRICALLY CONDUCTIVE CEMENT-BASED COMPOSITES

Basic cement matrix was modified by addition of carbon particles and other suitable materials to enhance its electrical conductivity and broaden application possibilities of thin-walled fibre-reinforced inorganic composites for elimination of electromagnetic field effect, heating of concrete trafficable surfaces and scanning of moving vehicle weight. One of targets of the project "Multifunctional composites of extraordinary properties on the base of inorganic nanocomponents" was to achieve the greatest electrical conductivity of a composite with minimal reduction of physical mechanical properties caused by addition of carbon particles. The paper deals with particular examples of applications for electrical cable line shielding and slipping hazard elimination on communications.
