Abstract
Cementing compositions are provided that comprise water, cement kiln dust, vitrified shale, zeolite, and/or amorphous silica, that utilize a packing volume fraction such that the solid particulate materials of the fluid are in a hindered settling state. Methods of cementing are provided that utilize compositions comprising water, cement kiln dust, vitrified shale, zeolite, and/or amorphous silica, that utilize a packing volume fraction such that the solid particulate materials of the fluid are in a hindered settling state.
