ABSTRACT
This study overcomes nanoparticle agglomeration in cementitious materials using a SiO2/Al2O3 [7:3] mixed sol system at 1.5 wt.%. The hybrid sol synergistically enhances cement paste performance through dual mechanisms: surface charge complementarity and steric hindrance enable molecular-level dispersion, while SiO2 consumes portlandite via pozzolanic activity and Al2O3 regulates hydration product morphology. Results show a 21.3 % increase in 28-day compressive strength versus control, alongside improved chloride/carbonation resistance. The optimized dispersion maximizes nano-filler densification and C-S-H nucleation acceleration. The 7:3 ratio balances SiO2 reactivity with Al2O3 amphoteric surface properties, forming interlocked microstructures. This interfacial engineering strategy establishes a nanoscale design framework for high-performance cement composites, demonstrating that ultraloading dual-nanoparticle systems can overcome traditional dispersion limits while enhancing multifunctional properties.
