The construction industry is a major contributor of CO 2 emissions. Carbonation, involving
the reaction of CO 2 with alkaline reactants, immobilizes CO 2 into thermodynamically stable …

Moist calcium silicate minerals are known to readily react with carbon dioxide (CO2). The
reaction products can cause rapid hardening and result in the production of monolithic …

Heavy metal-bearing waste usually needs solidification/stabilization (s/s) prior to landfill to
lower the leaching rate. Cement is the most adaptable binder currently available for the …

Solidification/stabilization is accepted as a well-established disposal technique for
hazardous waste. As a result many different types of hazardous wastes are treated with …

Alkali activation of fly ash by sodium silicate solutions, forming geopolymeric binders,
provides a potential means of treating wastes containing heavy metals. Here, the effects on …

The stabilization/solidification (S/S) of a municipal solid waste incineration (MSWI) fly ash
containing hazardous metals such as Pb, Cd, Cr, Zn or Ba by means of geopolymerization …

Hazardous heavy metals in Municipal Solid Waste Incineration (MSWI) fly ash are a threat to
the environment and ecosystems. The objective of the work is to investigate the solidification …

The mining industry manages large volumes of tailings, sludge, and residues that represent
a huge environmental issue. This fact has prompted research into valorization of these …

Red mud (RM) is a potential supplementary backfill material. However, little is known about
cemented paste backfill (CPB) preparation from reused RM. Here, the feasibility of Bayer RM …

Cement can treat a variety of wastes by improving physical characteristics (solidification)
and reducing the toxicity and mobility of contaminants (stabilization). Potentially adverse …
