INFLUENCE OF CARBON ADMIXTURES ON ELECTRICAL PROPERTIES OF INORGANIC FIBRE-CEMENT COMPOSITES

摘要

It is possible to achieve specific electrical properties by addition of certain components into a cement matrix.rnIt has ben found that to achieve specified electrical properties carbon particles of micro and nano-size arernmostly suitable. Though carbon fibres are less conductive than metal fibres, composites with carbon fibresrnhave been evaluated as better current conductors than composites with metal fibres. Structurally-technicalrnelements made of these newly composed fibre inorganic composites are able to shield againstrnelectromagnetic fields, to transform electricity to heat or to scan the weight of moving vehicles. This paperrndeals with design and selection of appropriate formulations for pavements or access ramps and describesrnmanufacturing of tempered element prototype and its operation in real conditions.
