利用粉煤灰、拜耳法赤泥制备贝利特硫铝酸盐水泥
Study on preparing belite sulfoaluminate cement using fly ash and Bayer red mud
摘要
Abstract
Fly ash and Bayer red mud are used as raw material to prepare belite sulfoaluminate cement.The effect of the introduction of Bayer red mud on the clinker sintering temperature, work performance and mechani-cal properties is studied.The mineral composition of clinker and mineral content by XRD is analyzed.The re-sults show that belite sulfoaluminate cement of performance can be prepared using fly ash and Bayer red mud. The introduction of red mud can reduce clinker firing temperature, certain amount of red mud can promote the formation of minerals of C4 A3 S and improve the compressive strength of concrete, which will decrease the strength when the introducing of red mud excesses 8 percent.When the content of red mud is 4 percent, com-pressive strength of prepared cement is 48.9 MPa,.关键词
