Preliminary Study of Structural Concrete made with the addition of multi-walled Carbon Nanotubes and Soil Nano Stabilisation 360 System

Abstract

The development of nanomaterials in recent years has allowed for the analysis of the possibility of modifying or improving the physical and mechanical properties in concrete manufacturing. Initially, a methodology for the dispersion of nanomaterials was established to homogenize the mixtures. Samples were prepared with varying amounts of MWCNT ranging from 0.05% to 0.25%, in combination with the SNS 360 system at 1% and 2%, alongside a control mix without nano-additions. The samples were fabricated using ordinary Portland cement (OPC) maintaining a water/cement ratio of 0.55. The results indicated a 30% improvement incompressive strength and xx% in tensile strength at 28 days. High compressive strengths were obtained 3 days after its manufacture, acting as an accelerator. At the same time,
increasing the percentage of nano materials reduced the slump value and workability. In addition, the permeability decreased significantly compared to standard concrete.Therefore, the concrete mixture with two nanotechnology-based materials demonstrates significant advantages over conventional concrete by being more resistant to compression, traction, exhibiting lower permeability, and achieving high compressive strengths in less time
