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.
