Abstract

This work falls within the scope of a genera! problem regarding the assessment of concrete manufactured from waste materials. The main objective is to study the long-term evolution of these materials during the leaching process, using the cellular automaton-based hydration model developed at the National Institute of Standards and Technology. The work is based on the analysis of mortars and ccment pastes containing experimental waste: Municipal Solid Waste Incineration fly ash (MSWI fly ash). The study therefore uims to develop a methodology for assessing concrete manufactUred from waste, and not to study a process or a formulation enabling the incorporation of the waste in concrete. The physical, chemical and mineralogical churacteristics of MSWI fly ash were first analysed to introduce them into the model. A simplified quantitative mineralogical composition of the ash was proposed. The performance charucteristics (setting times, compressive strengths, shrinkage, etc.) for mortars containing ash were then studied.
