An immobilisation mechanism for lead in fly ash subjected to mechanochemical treatment
Mechanochemical (MC) processes immobilise heavy metals in fly ash, a desirable outcome because recycled fly ash is commonly used in the synthesis of inorganic materials. We investigate the extent of immobilisation and the mechanism of lead (Pb) leaching during MC treatment of fly ash, using lead oxide (PbO) and lead dichloride (PbCl2) as model compounds. MC treatment of the fly ash inhibited Pb ...
Innovative fracture-resistant construction material from C&D waste aggregate, fly ash and recycled plastics
A laboratory investigation was conducted to evaluate the fracture behaviour of an alternative pavement foundation material containing cement stabilised reclaimed crushed aggregate, Class C fly ash and waste-plastic strip (high density polyethylene or HDPE) reinforcement. The primary objective of using strip reinforcement was to improve the tensile strength, crack resistance and toughness ...
Case study - High volume fly ash in the Madera project
Located on a fully wooded 44-acre site in Gainesville, Florida, directly adjacent to the University of Florida campus, Madera consists of 80 lots being developed by Green Trust, LLC, and built by three builders. In the spring of 2002, selected builders were invited to participate in a presentation and meeting with the Florida Energy Extension Service (FEES) which spearheaded the project for the ...
