Abstract

Introduction: Concrete's filler material gets strengthened over time by specific chemical reactions that harden it. Multi-walled carbon nanotubes (MWCNTs) are more frequently used as fillers than SWCNTs, owing to their lower cost of production and their superior reinforcement properties in cement composites.

Method: Mechanical properties like compressive strength, splitting tensile strength, and modulus of elasticity are proportional to the water/cement ratio (w/c) and are considered critical criteria in the design of structural elements.

Results: The aim of the present work was to prepare, characterize, and determine the effects that multi-walled carbon nanotubes (MWCNTs) can have on the mechanical strength of various matrix cementitious composites.

Conclusion: The results showed that the addition of multi-walled carbon nanotubes to the concrete greatly improved both its compressive strength and its splitting tensile strength.
