- Abstract
The effect of sludge dosage and sintering temperature on the properties of sintered bricks was studied by using municipal sludge to prepare sintered bricks. The results showed that the strength of sintered brick was significantly affected by the increase of sludge content. The strength of the test block with 15% sludge content meets the requirements of GB 26538-2011 "sintered insulating brick and insulating block". Different sintering temperature, sintered brick internal phase composition is not the same, the higher the temperature, the more glass phase. The increase of sludge content will change the internal structure of the test block, with more pores, the greater the connection between pores, the greater the heterogeneity of crystals, and ultimately lead to the greater the water absorption rate of the test block, so that the physical properties and durability of the test block become worse.
