Preparation of Sintering-expanded Haydite with Red Mud from Bayer Process
摘要
Abstract
Sintering-expanded haydite has been prepared by using red mud with glasses,fly ash and a little of other additive. The results show that the content of red mud and firing temperature ore main factors influencing the performances of haydite. The single grain compressive strength of haydite is 0.6kN,water absorption is 0.4% and apparent density is 1.31g/cm3 when the firing temperature is 1140℃ and the content of red mud is 50wt%. The haydite has very good glazy surface structure with closed pore structure. The main components of haydite are hematite,hibschite,anorthite,perofskite,nephline and vitreous.关键词
