Evaluation study on gas-phase passivation inhibiting the spontaneous combustion tendency of ferrous sulfide compounds by Yuanyuan Zhang, HaSung Kong, Ruixuan Hao, Qin Xu, Long Zhao

“…The results show that the entropy-weight method assigns dominant weights to the duration temperature in the room-temperature spontaneous combustion stage (ΔT1, 10.2%) and the activation energy in the high-temperature combustion stage (E3, 9.3%), indicating that the thermodynamic suppression effect, driven by the passivation mechanism, plays a more significant role than the changes in the microstructure. TOPSIS analysis reveals that the FeS sample passivated for 8 h with a 9% passivator concentration has the lowest spontaneous combustion tendency (composite score of 0.743), while the highest risk is associated with the sample passivated for 2 h with a 3% concentration (composite score of 0.341). …”

Experimental Investigation on the Effects of Coffee Husk Ash as Partial Replacement of Cement on Concrete Properties by Asmamaw Gedefaw, Begashaw Worku Yifru, Solomon Asrat Endale, Betelhem Tilahun Habtegebreal, Mitiku Damtie Yehualaw

“…However, it increases as the curing days increase, whereas the water absorption of the concrete increases as the CHA increases but decreases as the curing days increase due to the porous nature of the CHA. From the study microstructure of concrete using Fourier transform infrared spectroscopy and thermogravimetric analysis, differential thermal analysis results show that the C-S-H gel would be from 950–1100 cm−1 wavenumber and at 500oC, and the CHA sample was decomposed and mass loss was observed at 500oC. …”
