FOAMED LIGHTWEIGHT MONOLITHIC REFRACTORY COMPOSITION
A foamed lightweight monolithic refractory castable is provided. The castable includes one or more refractory aggregates as a main constituent, one or more foaming additives in a range of 0.1 wt % to 3.0 wt %, one or more cellulosic powder air-entraining additives in a range of 0.005 wt % to 2.0 wt %, one or more binders in a range of 1 wt % to 40 wt %, and one or more superplasticizers in a range of 0.05 wt % to 0.5 wt %. The refractory aggregates include at least one of alumina and silica. The foaming additives include at least one of alkylbenzene sulfonates, alkene sulfonates, and hydroxylalkane sulfates. The superplasticizers include at least one of sodium polyacrylates, naphthalene sulfonates, polyethylene glycols, polycarboxylates, polyacrylates, and polycarboxylate ethers.
