The paper discusses the utilisation of a by-product specifically a fly ash sourced from a landfill where it had been dumped over a period of several years. The fly ash had been produced from a coal burning power plant in Malta and landfilled in disused quarries in Bengħisa. The landfilled fly ash deposit dumped in the quarries is considered as an environmental hazard. The research addresses the potential use of the fly ash for recycling in the production of cement based materials particularly repair mortars. The paper presents the design and testing of repair mortars in which the fly ash is used as a partial replacement of cement. In order to improve the environmental resistance, the performance of the material with the addition of a crystalline admixture was assessed. The stabilisation of the fly ash in the mixture was verified through the assessment of physical-mechanical properties and through a microscopic examination of the microstructure of the mortar.
