In this paper, cement free high performance alkali activated slag-fly ash composites are designed by applying the modified Andreasen and Andersen particle packing model, and steel fibers of two lengths are applied for strength reinforcement and shrinkage compensation. The influence of the fiber length, dosage and hybrid on the fresh behavior, compressive strength, stress–stain behavior under flexural...
In this study, the mechanical strength, total porosity and corrosion performance of ordinary Portland cement (OPC), class F fly ash (PFA) and metakaolin (MK) alkali-activated mortars (AAM) reinforced with 1 and 2% mass fraction of scrap tire steel fibers (SSF) were investigated. The accelerated corrosion test comprised of immersion of specimens in a 5% NaCl solution and specimen electrical resistivity...
