Influence of Sintering Temperature on Performance of Red Mud Lightweight Ceramsite

Abstract:

The red mud lightweight ceramsite was made by using red mud, fly ash and bentonite, mixed with a certain amount of pore-forming agent and cosolvent, through the roasting process. Influence of sintering temperature to red mud ceramsite was studied. The microscopic morphology of red mud lightweight ceramsite damage fracture was analyzed by using scanning electron microscope and the roasting mechanism was investigated preliminarily. The results show that for the best sample, its apparent density is 724kg/m3, its bulk density is 574kg/m3; its cylinder compressive strength is 5.5Mpa, the water absorption is 8.6%.
