Effect of Nano-Silica Content on Compressive Strength and Modulus of Elasticity of High-Performance Concrete
The nano-silica (NS) particles trigger hydration reactions reduce the less stable components (Calcium hydroxide), and produce better quality pozzolan gel products in concrete. This process gives the concrete have a dense structure, early strength growth, increase compressive strength, flexural strength, splitting strength, water anti-permeability, and corrosion resistance. This article aims to research the influence of NS on compressive strength and modulus of elasticity of high-performance concrete. Nano-silica particles are added into high-performance concrete mixture with the contents 0.5, 1, 1.5, 2, 2.5 and 3% by weight of the binder. The addition of NS resulted in enhancing compressive strength and modulus of elasticity up to 1.5% replacement level. When the NS content is 2–3%, the compressive strength and modulus of elasticity increases nonsignificantly and tends to decrease compared to NS’s rate using 1.5%. The experiment results will build a relationship function between the modulus of elasticity and nano-silica content.
