Influence of Aggregates on Properties of Carbon Fiber Electrically Conductive Concrete for Deicing or Snow Melting

The problems for choosing crushed stones in making of carbon fiber conductive concrete for deicing or snow-melting are discussed. Three principles for crushed stones in the production of the slab must be obeyed. The coarse aggregates content must be kept to a low level, the standard ratio of cement-sand-stone should not be used and large broken stones are unsuitable. The influence of the aggregates content on the electrical conductivity, compressive strength and the flexural strength of the conductive concrete are analyzed.
