Abstract
This invention provides a lightweight ceramic composition which is characterized by an average bulk density between about 10-105 PCF, and a compressive strength between about 300-10,000 psi. In a preferred embodiment, this invention provides an extruded structural cellular clay product having pores which are substantially non-interconnected and elongated in a single directional configuration, and having a density gradient in at least one cross-sectional plane, in which gradient the higher density is in proximity to the outer surfaces.
