The Research on Heavy Metal Ions Curing and Its Influence on the Cement Hydration Process

It is the effective way to handle heavy-metal-ions in wastes with adsorption and curing function of cement-based materials.That is a research focus over many years.In this paper,the structural features of the main hydration products and its influence on adsorption and exchange foreign ions was analyzed.Through collecting domestic and foreign literature,it also summarized the existence form and curing mechanism of heavy-metal-ions(Pb,Cr,Cu,Zn,As,Co,etc.) in the hydration products,and the ions influence on hydration process.The insufficiency on studying heavy-metal-ions cuing in cement was also proposed.
