It is known that grinding is one of the methods of aluminosilicate wastes modification. The optimal modes of grinding under laboratory conditions were defined. Physical and chemical studies of the modified ash were conducted using X-ray phase analysis, DTA, and microscopy. It is shown that the modified ashes of thermal stations when used in the production of ceramic brick affect positively the performance properties of green brick and finished products.
