In some countries, more than 25 per cent of the ashes utilized has been used up in manufacturing bricks. It has been possible to replace conventionally used sand as a blend material to clay with either fly ash or bottom ash. In foreign tests, it has been established that their usability depends essentially upon the quality of sand and ash. Ash can be used to the best advantage together with the so-called rich clay containing plenty of clay material. In recent years, a new manufacturing process of bricks using ashes almost entirely as a raw material has been developed. One of the most important factors that argue in favor of their use is, for instance, the savings achieved in production costs, primarily in energy consumption, resulting mainly from the heat content of unburnt coal. The energy savings depending on the manufacturing process used may have been as much as 30 or even 50 per cent.
