Abstract

ABSTRACT

This research investigates the effect of incorporating nano-silica (NS) on the mechanical properties of rubberised concrete. Fine aggregate was replaced with rubber at a ratio of 0%, 10%, 20% and 30% by volume. A constant water to cement (w/c) ratio of 0.45 was used in all concrete mixes.  The influence of incorporating 0%, 1.5% and 3% of nano-silica (NS) to cement by weight on the basic properties of rubberised concrete, including density, water absorption, compressive strength, flexural strength, splitting tensile strength and drying shrinkage of samples, was studied. The results showed that the utilisation of NS in the rubberised concrete mixes enhanced the strength properties and decreased the drying shrinkage strain.
