Description
Summary:The effect of carbon-containing additives on the physical, mechanical and electrical properties of the fluoroanhydrite composition used for self-leveling floors has been investigated. Copper/carbon nanocomposite, crushed technogenic graphite and thermally expanded graphite were used as modifying additives in this research. A method for obtaining thermally expanded graphite was described; the efficiency of its introduction into the plasticized fluoroanhydrite composition was proven: the electrical resistance of the material decreased by 11 times with an insignificant drop in strength on the 7th day from 34.9 to 29.8 MPa (15%). Modification of the composition with copper/carbon nanocomposite did not prove to be effective, leading to a 3-fold decrease in the electrical resistance of the material accompanied by a 4-fold decrease in the compressive strength of the samples. Modification of the composition with micro-sized particles of technogenic graphite lead to a decrease in the strength of the material by 28% without affecting its electrically conductive properties.
