A bstract The use of combined treatments was found to Ix more efficient in improving the properties of clays than individual treatments, and the best results were obtained when the clay was pugged with steam and hot water with an addition of 0.2% of soda ash. This process lowered the water of plasticity 26%, the drying shrinkage 58%, arid the absorption 46.5%. The dry and fired strengths were increased 123% and 144%, respectively.
