The Preparation 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 foam stabilizer, through the roasting process. Influence of pore-forming agent on red mud ceramsite was studied. The microscopic morphology of red mud lightweight ceramsite damage fracture was analyzed by using scanning electron microscope. The results show that with 6% pore-forming agent, the apparent density is 731kg/m3, the bulk density is 547kg/m3; the cylinder compressive strength is 3.3Mpa, the water absorption is 9.7%.
