“…C-A-S-H, which immobilizes organic compounds and HMs, is also a key binding phase of alkali-activated materials (AAMs), e.g., alkali-activated calcium aluminosilicate [176,177]. Sodium hydroxide and sodium silicate are the most common activators to activate precursors-amorphous (calcium) aluminosilicate phases [178,179]. When precursors are calciumpoor, the key binding phase is sodium aluminosilicate hydrate (N-A-S-H), a nanosized gel, which also adsorbs toxic elements [180,181].…”

Municipal solid waste and cement manufacture are two sources of environmental justice issues in urban and suburban areas. Waste utilization is an attractive alternative to disposal for eliminating environmental injustice, reducing potential hazards, and improving urban sustainability. The re-use and recycling of municipal solid waste incineration (MSWI) ash in the construction industry has drawn significant attention. Incorporating MSWI ash in cement and concrete production is a potential path that mitigates the environmental justice issues in waste management and the construction industry. This paper presents a critical overview of the pretreatment methods that optimize MSWI ash utilization in cement/concrete and the influences of MSWI ash on the performance of cement/concrete. This review aims to elucidate the potential advantages and limitations associated with the use of MSWI ash for producing cement clinker, alternative binder (e.g., alkali-activated material), cement substitutes, and aggregates. A brief overview of the generation and characteristics of MSWI ash is reported, accompanied by identifying opportunities for the use of MSWI ash-incorporated products in industrial-scale applications and recognizing associated environmental justice implications.
