Resumo
This study focuses on the development of hydrophobic layer on Portland cement using
graphenoid materials to enhance impermeability and hydrophobicity. X-ray diffraction
analysis revealed that characteristic peaks associated with concrete remained intact,
indicating the presence of phases such as ettringite, calcium hydroxide, calcite, and
more. Remarkably, the application of graphenoid material produced by non-thermal
plasma resulted in the formation of carbonaceous structures with minimal impact on the
overall cement structure. Raman spectroscopy provided detailed insights into the
composition, highlighting the presence of specific and indicating boundary defects.
Moreover, contact angle measurements confirmed a substantial increase in
hydrophobicity for the graphene-coated cement, with an average angle of 117° +/- 4.72°
demonstrated graphenoid material layers deposited over structural defects, effectively
waterproofing and enhancing local hydrophobicity.
