ABSTRACT:
This invention relates to a method for making brick from shale or a mixture of clay and shale by adding to the shale or shale mixture an additive containing sodium bentonite, a water soluble anionic polyelectrolyte polymer, and, preferably, a water soluble dispersant. The additive increases the plasticity and the green strength of the shale or shale mixture so that high quality bricks can be produced from such raw material.
