摘要

Using iron tailings from northern Tangshan region of China as the main material, fly ash and clay as the accessories, fired bricks were prepared. The influences of iron tailings content, heating rate, firing temperature and holding time on water absorption and compressive strength of bricks were investigated the phases of fired bricks was characterized by XRD. The most suitable conditions is as follows: the range of the iron tailings content is 80%～95%, no more than 8°C/min has little effect on the properties of fired bricks, the range of feasible calcined temperature could be adjusted in 1020～1050°C for 1.5～2 h, which make the physical properties and durability of fired bricks accorded with Chinese Fired Common Bricks Standard (GB/T5101-2003). The main mineral phases mainly constituted the mechanical strength of fired product are hematite, quartz, anorthite and augite.
