Abstract

This paper evaluates the effect of nano-metakaolin on compressive strength and durability properties of cement mortar and concrete. The Portland composite cement was replaced with 3%, 5% and 10% nano-metakaolin (by wt.). The compressive test results show that the optimum amount of nano-metakaolin in the mortar and concrete mixes is 10%. There is also a great improvement on water sorptivity of concrete with nano-metakaolin. The result shows that concrete with nano-metakaolin 10% has sorptivity values of 6 and 5 (x10-4mm/min1/2) at 7 and 28 days, which is 76% and 68% lower when compared to the sorptivity of cement concrete. In this study, microstructure and phases identification results are also presented. Results show the effectiveness of nano-metakaolin in accelerating the pozzolanic activity by consuming calcium hydroxide (CH) and improving packing density.
