Self-Compacting Cementitious Composites with Heavy Fuel Fly Ash Replacement

Sustainability in construction is related to the use of industrial by-products, such as fly ash (FA). FA varies chemical/mineralogical composition, depending on raw materials burnt during its production. While produced from coal-fired power stations extensively used cementitious composites, heavy oil firing fuels (e.g., mazut or diesel) remains largely unused. This paper focuses novel fuel (HFFA), a replacement Class F FA, high-volume self-compacting composites. Two different grain size distributions HFFA were quantities 5–15% w/w cement and for production The assessment physico-mechanical properties microstructure end-products at curing ages suggests that may be ?10% w/w, without any negative effects. In fact, quantity distribution HFFA, this even improve some long term, provided careful mix design adopted. findings show potential sustainable reuse are beneficial incorporation into codes.
