Corundum-silicon carbide-bearing concrete parts made using a liquid glass binder
Using the method of simplex-grid experimental planning and the generalized function of desirability, the range of optimum compositions of liquid glass bonded corundum-silicon carbide-bearing concretes possessing the specified microstructure and properties was determined. The properties include ultimate compressive strength, open porosity, refractoriness, linear shrinkage after firing, phase behavior under thermal cycling conditions, and thermal shock resistance. Materials were obtained from silicon carbide waste products from thermal insulation production, scrap of chamotte-silicon carbide saggers, and corundum waste products from refractories and abrasives plants. The improved service characteristics of the concretes are due to their phase composition and to the presence of coarse corundum grains.
