Aging mechanism of foamed asphalt under the coupling effect of salt-water-temperature by Na Liu, Wenan He, Changming Wang, Kun Zhou, Hailiang Liu

“…The micro-morphology, modulus, adhesion and chemical functional groups of the specimens were obtained from the tests, and the correlation between the micro-property indexes and the macro-property indexes was analyzed. The results show that the microstructure of foamed asphalt tends to ‘homogenise’ as the number of freeze-thaw and wet-dry cycles increases; the roughness index decreases; the modulus and adhesion increase; the aromatic and sulphoxide indexes become greater. …”

Preparation of SiC/Al2O3 composite materials from coal fly ash by LI Zi-yong, WU Chun-han, YU Qing-chun, ZHOU Yue-zhen, LI Wei, YANG Bin

“…By using coal fly ash as a raw material and graphite as a reducer in the protective atmosphere of argon,SiC/Al2O3 composite materials were synthesized by carbothermal reduction.The reaction process of reduction of the coal fly ash was studied,and its influencing factors were investigated.The composition of products obtained at different temperatures was analyzed by X-ray diffraction,and the microstructure was observed by scanning electron microscopy and energy dispersive spectroscopy.The results show that the phases of quartz and mullite in the coal fly ash are almost completely reactive at 1673 and 1773 K,respectively.With increasing temperature,the contents of SiC and Al2O3 increase,and the suitable temperature condition is 1773 to 1873 K.The extension of holding time is good for the formation of SiC and Al2O3,and the appropriate holding time is 3 to 4 h.Increasing the carbon content has positive effect on the formation of SiC and Al2O3,and the optimum molar ratio of C/Si is 4 to 5.In the prepared SiC/Al2O3 composite materials,SiC is homogeneously dispersed in the products,and its granularity is less than 20 μm.…”
