Strength and durability evaluation of Nano blend concrete matrix for sustainable development

Abstract: The present research study characterised the performance of various types of nanomaterial concrete for the evaluation of strength and durability performance by conducting compressive strength, water absorption and sorptivity. The durability test measures the amount of water that penetrates the matrix when exposed to aggressive environmental agents. The formulated concrete blends is made by partially replacing ordinary Portland Cement (OPC) with nanomaterials such as multi-walled carbon nanotubes (MWCNT), titanium dioxide (TiO2) and copper oxide (CuO) in various proportions. The nanomaterials are replaced 0.1%, 0.25% and 0.5% in OPC. The destructive strength analysis is done at 28 days of curing and durability was tested upto 56 days in the interval of 28 days curing period. The results were interpreted with the analysis using ANSYS software by applying the various preliminary conditions. From the analysed results, the mix with 0.5% of the Carbon Nano Tubes, TiO2 and CuO present by weight of the cementitious materials exhibited noticeably less water absorption value of less than 3% and less sorptivity value. According to the analysis done, the mixture that has Nano materials added at a rate of 0.5% is the best composition. The same mixture has also shown to be extremely durable making it suitable for use as engineering concrete in challenging conditions.
