Utilization of disperse metalworking wastes in the building ceramic production

Abstract

This work is aimed at studying of possibility to use disperse metalwork wastes for building ceramic products manufacture. We performed the overall study of the composition and properties of the steel waterjet cutting disperse wastes and their behavior as part of the ceramic paste and baked ceramics. We noticed a positive effect of the wastes’ additives on the ceramic properties for three types of polymineral clay raw materials: reduction of air and fire shrinkage, strength improvement at optimal wastes content in the mixture, possibility to get quality baked ceramics at 900-950°C, improvement of the material hydro physical properties and possibility to vary the products’ colors. The received results allowed us to make a conclusion about possibility to use the steel waterjet cutting disperse wastes in the building ceramic production as a polyfunctional component: effective thinning agent, fluxing agent and component for volume coloring.

Computer thermodynamic modeling of the producing silicon alloys from the Kentau Combined Heat and Power Plant ash

“…To date, scientific and technical developments are known for the use of ash as the main component or an additive in the production of building bricks, binders, thermal insulation materials, glass, glass-crystalline materials, agloporite, etc. [8][9][10][11][12]. At the same time, the ash utilization degree in Kazakhstan reaches only 2% of the annual output.…”
