Abstract: A process for making a sintered article including the steps of: (a) preparing a particulate mixture; (b) contacting the particulate mixture to water to form a humidified mixture; (c) pressing the humidified mixture to form a green article; (d) optionally, subjecting the green article to an initial drying step; (e) subjecting the green article to a firing step in a kiln to form a hot fused article; and (f) cooling the hot fused article to form a sintered article. The particulate mixture includes: (i) at least 20 wt % coarse coal combustion fly ash; and (ii) at least 30 wt % clay, wherein the coarse coal combustion fly ash has a particle size in the range of from greater than 150 μm to less than 250 μm.
