•Colloidal Nano-Silica is used as partial replacement of cement for production of concrete mixes.•Recycled aggregate concrete has inferior mechanical properties as compared to that of control concrete.•Recycled aggregate concrete with 3% Nano-Silica has compressive strength similar to that of natural aggregate concrete.•Improvement in tensile strength of recycled aggregate concrete is observed with the incorporation of Nano-Silica.•Non-Destructive parameters are also enhanced with addition of Nano-Silica.
The present work addresses the effect of incorporation of colloidal Nano-Silica on the behavior of concrete containing 100% recycled coarse aggregate. In this study, concrete mixes containing both natural and recycled aggregate are produced by replacing a fraction of Portland cement 0.75%, 1.5% and 3% of colloidal Nano-Silica respectively. The results of experimental investigation depicts that compressive strength, tensile strength and Non-Destructive parameters are enhanced due to addition of NS. Moreover, the study reveals that the characteristics of recycled aggregate concrete resembles with that of natural aggregate concrete with the addition of little amount (3%) of Nano-Silica.
