This paper introduces the process of firing bricks with high content sludge and fly ash at low tempera-ture.The following advantages can be obtained by using this process to fire bricks:increasing the content of sludge and fly ash;Compared with the original sintered bricks,the firing temperature is reduced by about 10%,saving energy consumption;The fired bricks not only have excellent physical properties,but also have self-cleaning properties and good stain resistance;It does not dissolve heavy metals,which can make the sludge be effectively utilized.
