Effect of Al2O3 Nanoparticles on the Workability, Strength, and Durability Properties of High-Strength Concrete

Concrete's mechanical qualities and endurance might be greatly enhanced by recent developments in the technology, especially via the investigation of nanoparticles. The purpose of this research is to evaluate the effects of adding Nano Al2O3 particles to M60 grade concrete mixes on mechanical qualities, durability traits, and compressive strength. Nano Al2O3 has an average diameter of 15 nm and is tested at various weight percentages of 0.5%, 1.0%, 1.5%, and 2.0% in accordance with IS 456-2000 standards. The experimental effort focused on compressive strength and durability evaluations by conducting systematic comparisons between ordinary cement concrete and NanoAl2O3 blended concrete. The research provides a comprehensive evaluation of the contributions of fly ash, silica fume, and metakaolin to concrete performance by examining their synergistic effects. The findings show that adding NanoAl2O3 significantly increases the concrete's compressive strength and durability, which enhances the mechanical qualities of high-strength concrete. Important conclusions on the efficacy of NanoAl2O3 as an additive are presented in this work, promoting robust and sustainable infrastructure solutions. The expected benefits to society include long-lasting buildings, lower maintenance costs, and safer construction practices, which will enable the development of complex and sustainable built environments. This research shows how nanotechnology may be included into concrete formulation to support sustainable building methods that strengthen resilient infrastructure and encourage long-lasting built environments.
