Manufacturing of sintered lightweight aggregate using high ...
Fly ash is the largest source of industrial solid waste in China. Fly ash with its high content of unburned carbon has to be discarded in landfills and cause environmental problem. To reduce the environmental impacts, lightweight aggregate (LWA) was manufactured utilizing highcarbon fly ash (HCFA) (loss on ignition, LOI = ∼%).

Pelletized fly ash lightweight aggregate concrete: A ...
nbsp; The production of concrete requires aggregate as an inert filler to provide bulk volume as well as stiffness to concrete. Crushed aggregates are commonly used in concrete which can be depleting the natural resources and necessitates an alternative building material. This led to the widespread research on using a viable waste material as aggregates. Fly ash is one promising material ...
