GRAPHENE OXIDE-MODIFIED CONCRETE

Given that concrete is currently the most widely used building material, its strength and durability are essential qualities. Recent advances in new nanoscale fibers like as carbon nanotubes and graphene oxide have improved the performance of concrete. Graphene oxide (GO) is a two-dimensional planar sheet of compressed carbon atoms in a honeycomb configuration with thickness 0.335 nm. GO is a promising nanomaterial due to its unique properties, namely, it has received international attention for its outstanding mechanical, optical, and thermal properties. In addition to regulating the secondary hydration mechanism, adding GO to concrete improves its mechanical performance, durability, self-healing, and other multifunctional characteristics. This study presents an investigation of the properties of concrete with GO addition. Four different concrete mix designs were prepared. GO was added in quantities of 0.01, 0.02, 0.03, and 0.06 %. Hydration routes were analyzed by differential thermal analysis. Mechanical strengths were tracked in duration od 28 days and frost resistance with deicing salts during 56 cycles.
