A POROUS REFRACTORY ARTICLE
A porous refractory article including greater than 90 wt % coal combustion fly ash. The coal combustion fly ash is in the form of an interconnected particulate lattice structure, and wherein greater than 50% by volume of the coal combustion fly ash particles within the particulate lattice structure have a particle size of greater than 150 μm. The article has: (a) an apparent porosity of from 30% to 50%, (b) a porosity such that the maximum pore size is less than 500 μm; (c) a cold crushing strength of at least 4.0 MPa; and (d) a thermal conductivity of less than 1.5 W/(m·K).
