Coal mine filling requires a safe, lightweight, and high-strength material, but current commonly used aeration agents, such as hydrogen peroxide, which produces the combustible gas O2, aluminum powder, explosive H2, are not suitable for coal filling. In this paper, new inorganic composite agent, namely sodium bicarbonate potassium sulfate, inert CO2, was developed. The effects of agent admixture (at contents 0%, 2%, 4%, 6%, 8%) on properties fluidity, setting time, compressive strength,...
Fly ash stands as the primary by-product stemming from coal-fired power generation. China has produced around 650 million tonnes of fly annually in recent years, with a comprehensive utilization rate approximately 70%. Nevertheless, heterogeneous nature inherent to curtailed its widespread application and led suboptimal rates. This study aims increase ash's glass phase content through heat treatment. Through investigation utilizing various testing methodologies such QXRD, SEM-EDS, TG-DTG,...
