EFFECT OF NANO SILICA ON PROPERTIES OF CONCRETE
This study presents experimentally the collective consequence of using nano silica (NS) on mechanical properties of tough concrete. NS is cast-off as partial cement substitution by 1,1.5,2 wt% . Mechanical properties of hardened concrete are assessed expending different mixtures between NS. Important enhancement in the mechanical properties of concrete is experiential with NS due to its high pozzolanic activity approving the creation of advanced quantity of C–S–H gel in the existence of nanoparticles. Employing 2 wt% NS due to to improves properties of hardened concrete in increasing compressive strength, splitting strength, modulus of elasticity and flexural strength compared to samples without either NS.
