Özet:

 This study investigated the influence of mineral admixtures fly ash, silica fume, metakaolin and curing conditions water immersion, polyethylene glycol, gunny bags, accelerated curing on the properties of self-compacting concrete SCC. The rheological properties, compressive strength, chloride penetration resistance, and microstructure were evaluated. Incorporating mineral admixtures improved the workability, strength up to 53 increase, and durability of SCC compared to plain mixes, with 20 metakaolin replacement optimal. Water immersion curing enhanced the compressive strength 315 increase and chloride resistance up to 30 decrease in migration coefficient owing to improved hydration and microstructural refinement. Mineral admixtures reduced the sensitivity of SCC to the curing method. Microstructural analysis showed higher density and additional C-S-H phases with mineral admixtures under wet curing. The study demonstrates that optimized SCC containing appropriate supplementary cementitious materials and proper external curing can achieve high performance.
