This work enunciates the effect of Multi-Walled Carbon Nanotubes (MWCNTs) as an addition to concrete subjected to normal environment and adverse environment. The MWCNTs are dispersed in water in the range of 0 to 0.25 % by weight of cement. The dispersed MWCNTs are added in concrete during its manufacturing process, and get cured for 28 days. Then portion of the samples are tested for its compressive strength, further samples are placed in exposed conditions, such as 5% concentrated sodium chloride solution and 5% concentrated sulphuric acid solution for a period of 4 weeks and 8 weeks respectively. The effect of this exposure is studied through changes in the weight density and compressive strength of the samples. All the exposed and unexposed samples were studied for its microstructural behavior through scanning electron microscopy. Ultimately, this work elucidates the influence of MWCNTs in the resistance of concrete under adverse environmental condition.
