Abstract: | The current research work is based upon the experimental study of the effect of the use of nano-sized particles of colloidal nano-silica (NS) on various properties of concrete. The concrete mixes are designed by substituting cement with 0.75%, 1.5% and 3% of colloidal NS. The analysis of experimental outcomes of this investigation illustrates that the compressive and tensile strength is enhanced with the increasing NS (%). Moreover, increase in density and decline in volume of voids and water absorption have been found due to the introduction of NS in concrete. Increase in mechanical properties and improved non-destructive test results indicates the qualitative improvement in concrete owing to the incorporation of NS. However, the inclusion of NS has no substantial impact on modulus of elasticity of concrete. |
