“…Wang et al (2015) found that adding 0.05% GO to cement pastes boosted the compressive strength by 40.4% and flexural strength by 90.5% [42]. Other researchers corroborated this by reporting that GO improved the strength and hardness of cement composites [24,25,43,44]. The compressive strength of cement paste containing 0.06% GO grew by 58.5% after 28 days, while the flexural strength of the mix with 0.04% GO was raised by 67.1%, according to their findings.…”

“…Nanofibers and nanotubes have been used as additives in cementitious composites and have been shown to increase mechanical properties [22][23][24][25][26]. However, due to a lack of interfacial regions between the nanoparticles and the cementitious materials, these carbon compounds were unable to achieve a complete bonding with cementitious materials [27].…”

The usage of industrially generated graphene was explored in this work, with an emphasis on dosage effects on durability, as well as the mechanical and microstructural properties of both concrete and mortar (0%, 0.1%, and 0.2% in concrete and 0%, 0.07%, and 0.15% in mortar). Based on the mix design for wastewater infrastructure, the results showed that adding graphene to both concrete and mortar enhanced 28-day compressive strength by 10–20%, with the best admixture level being 0.02–0.1%. Graphene reduced the AVPV of mortar by 11.7%, and concrete by 19.3% at the optimal dosages, likely by reducing the number or size of pores in the paste. The 0.2% and 0.15% graphene reinforced concrete and mortar showed significant sulfate resistance, by reducing 62% and 60% of extension respectively, after exposure to a sulfate solution for 16 weeks.
