AN OVERVIEW OF PORE FORMING ADDITIVES USAGE IN FIRED CLAY BRICKS
For the production of vertically perforated bricks with very good thermal insulation properties it is necessary to increase porosity of ceramic body. The most effective way to achieve this is the addition of organic substances into the clay mass. During the firing process combustion of these substances occures, leaving behind a large number of fine...

EFFECT OF ADDITION OF COAL FROM COAL MINE “KAKANJ” ON PROPERTIES OF BRICK CLAY “RAPAJLO”
A coal dust is added to brick clay mainly to save energy and increase porosity. This paper examines the influence of coal from Coal mine "Kakanj", in the amount of 10% and 20%, on some physical and technological properties of brick clay "Rapajlo". The impact of coal on the plasticity of clay, and the characteristics of dried and fired samples was i...
