摘要:
Class F fly ash (FA) is often limited in its application in the concrete industry due to its low hydration reactivity. This study explores the synergistic utilization of municipal solid waste incineration fly ash (MSWIA) and FA to valorize these two industrial waste streams for application in the concrete industry, aimed to reduce the carbon footprint associated with extensive cement use. The study proposes replacing part of the cement with MSWIA and Class F FA, with a baseline mix ratio of MSWIA: FA: Cement = 40 %:40 %:20 %. In addition, silica fume (SF), nano-montmorillonite (nMMT), and calc...
