The Use of Bottom Ash in the Manufacture of Clay Face Brick

Figures 4 and 5 illustrate the influence bottom ash has on the dry and fired micro-structure of the brick body. The bottom ash increased the median pore diameter by some 86%. The dry permeability and resultant drying rate and hence drying sensitivity of the body is influenced by this parameter. Production experience has shown that the bottom ash
