Preliminary Investigation on the effect of cement replacement by residues from the incineration of non-hazardous waste on strength and Alkali Silica reaction

Abstract
Rapid industrialization and urbanization have resulted in excess resource usage and the generation of a large volume of waste, which mainly end up in landfills. Both issues can be solved with a cradle-to-cradle approach, by utilizing waste residues as raw materials for the production of new products. Around 130 million tonnes of municipal solid waste are incinerated yearly, mostly in developed countries. The composition of the resulting ashes makes it possible to be use them as raw material in cement production or as supplementary cementitious material (SCM). Major hurdles for the utilization as SCMs are the presence of elemental aluminium, chlorides and sulphates. Elemental aluminium causes expansion at early ages. Despite this negative influence, the presence of aluminium has the effect of reducing alkali silica reaction (ASR), the latter being a major durability problem. When used as a SCM, the pozzolanic reaction reduces ASR both by depleting portlandite available and forming calcium aluminate phases like C-A-S-H, and also by inhibiting dissolution of silica by adsorption of alumina on the surface of silica. Mortars in which 25% of the Portland cement was replaced by MSWI ashes with varying aluminium contents were produced. The reactive aluminium content in each ash was experimentally quantified. The resulting susceptibility of the mortar mixtures made was assessed using the well-known Oberholster test. For none of the tested compositions the 0.1% limiting value for expansion was exceeded.
