摘要:	This study investigated the feasibility of reusing wastewater sludge ash in construction materials to replace partial materials Wastewater sludge sampled from thermal power plant was burned into sludge ash at 800 degrees C in the laboratory The sludge incineration ash has low heavy metal including Pb, Cd, Cr and Cu, so it belongs to general enterprise waste The chemical composition of sludge incineration ash was summed up in SiO(2), CaO, Fe(2)O(3) and MgO Then the wastewater sludge ash is also found to be a porous material with irregular surface When the sludge ash was used to replace mortar or concrete cement, its water-adsorption capability will result in the reduction of mortar workability and compressive strength Cement is being substituted for sludge ash, and 10 percent of sludge ash is more appropriate Sludge ash is reused to take the place of construction materials and satisfies the requests of standard specification except for higher water absorption
