Özet
This study explores the use of silicene as a nanoadditive in
cementitious composites, focusing on its impacts on mechanical
properties and microstructure. Synthesized 2D silicene was characterized
using HRTEM, FTIR, and XRD techniques. To assess the mechanical
performance, varying amounts of silicene (0–5 wt%) were incorporated to
cement and flexural and compressive strengths were tested at 7 and 28
days. Microstructural modifications in cement paste were analyzed using
SEM, 3D topographical mapping, and image processing. At 2% silicene, the
increased C-S-H densification and the refined morphology were confirmed
by higher pixel correlation, smoother surface topology, and enhanced
statistical image analysis metrics. Mechanical results indicated that
incorporating 1–2% silicene provided the optimum content, enhancing
28-day compressive and flexural strengths by up to 6.4% and 23.6%,
respectively. Therefore, the results present the potential use of
silicene for the first time as a novel nanoadditive for cementitious
composites with experimental evidence showing improvements in both
strength and microstructure, and are expected to contribute to the
expanding body of literature on the use of nanomaterials in cement-based
composites.
