        abstract = {Self-compacting concrete (SCC) requires a high volume of fine materials to achieve adequate flowability and segregation resistance, which may compromise its mechanical performance and long-term durability. The incorporation of nano-silica (NS), owing to its ultrafine particle size, high pozzolanic reactivity, and nucleation effects, offers a promising strategy to overcome these limitations. This study presents a comprehensive experimental evaluation of the influence of nano-silica on the rheological behaviour, mechanical strength, and durability performance of SCC. Cement was partially replaced with nano-silica at varying dosages, and the resulting mixes were characterized through standardized fresh-state tests including slump flow, T50 time, V-funnel flow, L-box passing ratio, and J-ring flow diameter to assess deformation capacity, filling ability, and passing ability.
Hardened-state performance was evaluated through compressive strength, splitting tensile strength, flexural strength, and modulus of elasticity at multiple curing ages. Durability assessments included water absorption, sorptivity, rapid chloride penetration (RCPT), sulphate attack resistance, acid attack resistance, and carbonation depth. Microstructural investigations using Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) were conducted to analyse hydration products and pore structure refinement},
