The Performance of Alkali-Activated Self-Compacting Concrete with and without Nano-Alumina

The environmental pollution crisis has infiltrated all aspects of life, making it hard to avoid the hazards. To address this, is essential recycle industrial waste through green concrete technology, such as ground-granulated blast furnace slag (S), silica fume, and fly ash (FA). In this study, effect nano-alumina (NA) on fresh hardened stag and/or slag-based alkali-activated self-compacting (A-ASCC) cured in an ambient environment was investigated. Three different types binders were used: 100% slag, 50% ash, ash. Four ratios (0%, 0.5%, 1%, 1.5%) used partial replacements for binder materials. characteristics A-ASCC evaluated by indicating slump flow, T50 value, V-funnel, L-Box tests. mechanical properties measuring compressive strength, flexural tensile splitting strength test values assess qualities state. Scanning electron microscopy (SEM) also clarify microstructure specimens. Regardless materials used, addition NA a negative state performance. performance significantly improved incorporation NA. with showed better than other However, highest strengths achieved 1% FA, maximum 1.5% Furthermore, using increases setting time may be produce environment.
