Abstract
The possibility of obtaining low-cement low-carbon periclase concretes with various ultrafine carbonaceous components has been studied. It is shown that it is possible to obtain periclase-carbon castable containing up to 1 wt. % ground waste from the production of high-molecular graphite fiber. According to the results of the data study, it was found that with an increase in the carbon content from 1 to 5 %, the water demand of the mixture increases (from 6,25 to 10 %), which leads to a decrease in strength, density and an increase in the castable porosity. Also, the developed periclase-carbon castables high slag resistance is shown in comparison with ordinary periclase-carbon products.
