Effect of Activator Modulus on the Performance, Reaction Products, and Microstructure of Biomass Power Plant Ash-Based Alkali-Activated Binders

Biomass power plant ash (BPPA) is an emerging solid waste with considerable potential for resource utilization, whereas its low reactivity limits its direct application as a cementitious precursor. In this study, BPPA was blended with ground granulated blast furnace slag (GGBFS) to develop an alkali-activated binder...

Thermo-Hydro-Mechanical (THM) Coupled Model for Gas Extraction from Deep Coal Seams and Factors Influencing the Effective Extraction Radius

Gas extraction from deep coal seams is strongly affected by high geothermal temperature, high gas pressure, and high in situ stress, making accurate prediction of the effective gas extraction radius important for optimizing gas extraction parameters. In this study, a thermo-hydro-mechanical (THM) coupled model incorpor...
