The preparation and micro mechanism of brick materials with iron tailings in Tanshang area

摘要

This paper discussed the experimental results of exploiting brick materials with iron tailing materials in Tanshang area. Through preparation of iron tailing bricks, the technical flow and production proportion was obtained. The results show that a burning- and steam curing- free brick product with a compressive strength of 28.30 MPa and Flexural strength of 5.63 MPa as the following: iron tailing; fly ash; sand; CaO; gypsum; cement. And long- term properties of a burning- and steam curing- free brick is also studied by experiments in this paper. Put forward a new technique of making materials with iron tailing. At the same time, the micro mechanism of iron tailing brick was also studied with X- Ray Diffractometer (XRD) and Scanning Electron Microscope (SEM).
