Clay bricks and dense clay bricks are different refractory bricks, the difference is in porosity. The porosity of clay bricks is about 26%. The aluminum content is 40%-55%, and the bulk density is 2.1-2.15g/cm3. The porosity of fine clay bricks is less than 18%, and the bulk density is greater than II {{X}} 2G / cm {{{IX}} inferioribus et poros, fortior gerunt resistentia.
