Антистатичні покриття із електропровідного бетону

Abstract

In this paper, it is proposed to use metal-saturated concrete as an antistatic coating. Such a coating will provideeffective protection from the occurrence of explosions and fires in especially dangerous premises. A fairly simple technology for producing an antistatic coating from an electrically-precast concrete is proposed, which does not requireexpensive special materials and equipment. As the electrically conductive filler, dispersed slag of SHX-15 steel wasused. This filler is a waste ball-bearing production and is practically not processed due to the high dispersity and thecontent of lubricating-cooling substances. As a result of the conducted researches it is established that from electricallyconductive concrete products with a wide range of electrical and mechanical characteristics can be made. On the basisof the whole complex of experimental studies, it has been found that electroconductive concrete on a large filler with avolume concentration of the electroconductive phase 0.3-0.4 is best suited for the production of an antistatic coating thatmeets the requirements for electrical conductivity, physico-mechanical and aesthetic characteristics.
