Abstract：An inorganic cementing material was prepared from various industry solid wastes,such as coal gangue slag,fly ash,magnesium slag,calcined lime and gypsum,etc. The aim is to replace the traditional Portland cement. This way is expected to avoid high energy consumption and high carbon dioxide emission during production of Portland cement. Every composition is ana-lyzed by XRF and XRD. The physic-chemical properties of obtained products were measured by relevant national standards. The results show that inspired action of calcium hydroxide to coal gangue slag and fly ash can greatly improve the strength of this cementing material. The compressive strengths at 3 d,7 d,and 28 d are 14.2 MPa,22.4 MPa and 42.1 MPa,respectively.
