Abstract

This work falls within the scope of a general problem regarding the assessment of concretes manufactured from waste materials. The main objective is to study the long-term evolution of these materials during the leaching process, using the cellular automata based hydration model developed at the National Institute of Standards and Technology. The work is based on the analysis of mortars and cement pastes containing experimental waste: Municipal Solid Waste Incineration fly ash (MSWI fly ash). The study therefore aims to develop a methodology for assessing concretes 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 characteristics of MSWI fly ash were first analyzed to introduce them into the model. A simplified quantitative mineralogical composition of the ash was proposed. The performance characteristics for mortars containing ash were then studied.
