Abstract
Immobilization of hazardous waste substances in a portland cement matrix is considered a major solidification method, which is no doubt due to the simplicity of the process and its low cost. However, the relatively high porosity of the cement matrix, which could lead to considerable leaching, has created a demand for improved portland cement matrices. In this regard, a research project has been sponsored by the Gulf Coast Hazardous Waste Substance Research Center. The overall objective of this study is to develop latex modified cement systems to treat inorganic and organic wastes. A preliminary study on stabilizing/solidifying inorganic waste (lead and chromium) with latex modified cement has shown very encouragmg results.
