Abstract: Combined with metakaolin as Al-correcting material, tungsten tailing was used as the main raw Si-Al material for geopolymer synthesis.In order to obtain the best autoclaved curing regime, orthogonal tests were conducted on condition that curing pressure, curing time and pressure relief time were acted as the affecting factors, and 7-day compressive strength of geopolymer was employed as index of evaluation.Besides, microstructure of the typical geopolymer samples were characterized by SEM and XRD.The results show that, curing pressure had the greatest influence on compressive strength of geopolymer; geopolymer can reach the highest compressive strength of 31.13 MPa when curing pressure was 0.8 MPa, curing time was 60 min and pressure relief time was 40 min; microstructure analyses indicated that, appropriate autoclaved curing regime can enhance dissolution of low-reactive Si-Al components from raw materials, then increase cementitious property and improve microstructure of geopolymer.
