With the rapid growth of the population and urbanization, the demand for industrial production has continued to increase, and industrial solid waste has become more and more abundant. Industrial solid waste mainly includes fly ashes, slags, tailings, red mud, bottom ashes and other wastes, which account for approximately 80% of the total waste produced on Earth. Industrial wastes generally contain various heavy metal components such as Pb, Zn, Cu, Cd, Cr, As, Ba and Mn. The low recycling rate of solid waste result...

A novel composite matrix composed of Portland cement (PC) and municipal solid waste incineration ash (MSWIA) was developed for the simultaneous immobilization of three heavy metals - Ba, Pb and Zn. The main motivation for the research was to exploit and reuse MSWIA to design alternative composite matrix with the ability to immobilize hazardous pollutants, such as heavy metals, which might be used as filler for the cement-based construction materials. In composition of prepared composite matrix, MSWIA was used as a...
