Ternary binder incorporating CFBC fly ash: microstructure evolution and micromechanical strength predictions
Original language description
Fly ash from circulating fluidized bed combustion (CFBC) can be utilized in a ternary binder system which exhibits hydraulic properties. The studied ternary binder consists of CFBC fly ash, conventional fly ash and Ca(OH)2 activator [1]. The paste yields compressive strength 32 MPa after 28 days of standard sealed curing. Volumetric evolution of phases during hydration were quantified using XRD analysis, differential thermal gravimetry, porosimetry and electron microscopy. A four-scale micromechanical model spanning nm-mm scales was employed to predict evolution of compressive strength [2], taking into account active contribution of C-S-H and ettringite on strength gain. Experimental and micromechanical model open a way for further optimization and utilization of such sulphur-rich energetic by-products with long-term volume stability. [1] P. Hlava'cek, R. Sulc, V.
