| Abstract: | This paper studied the preparation of non-burning brick by using used magnesia aluminum spinel brick stripped steel slag and used magnesia aluminum spinel as the main raw materials,supplemented with cement.The influence law of raw material ratio and preparation process on the microstructure and mechanical properties of unburned bricks was mainly studied.Optimal raw material ratio and preparation process for the waste magnesia-alumina spinel brick-based non-burning bricks were obtained.The stripped steel slag and used magnesium aluminum spinel accounted for 90%of the total material,cement 10%,molding pressure 15 MPa,room temperature curing for 28 d.The highest compressive strength and flexural strength of the prepared solid waste-based unburned bricks were 9.57 MPa and 4.86 MPa,respectively. |
