초록
High-strength ceramsite was prepared by using demagnesium boron mud and oil shale (OS) semi-coke as the main rawmaterials, Na2SiO3 as binder, and Na2CO3 as foaming agent. In the ceramsite with a 1:1 ratio of demagnesium boron mud andOS semi-coke, 3% Na2SiO3, and 10% Na2CO3 sintered at 1070 oC, the porosity, apparent density, and compressive strengthreached 22.63%, 1398.33 kg/m3 and 11.50 MPa, respectively. Na2CO3 played a decisive role in the sintering of high-strengthceramsite. Thermogravimetric analysis and X-ray diffraction results showed that the gas produced by raw meal during theheating process reduced the apparent density of ceramsite, and that new minerals such as albite and forsterite were producedduring the firing process. The forsterite formed islands within an albite framework, thereby strengthening the ceramsite.
