The　addition　of　graphene　and　its　derivatives　can　enhance　the　mechanical　and　functional　properties　of　cement-based　composites,　but　most　of　the　current　technologies　have　limited　dispersion　and　are　costly.　The　creation　of　a　cost-effective　graphene-reinforced　cement　material　with　uniform　graphene　dispersion　remains　difficult.　We　used　glucose　as　an　economical　carbon　source　to　induce　the　in-situ　formation　of　graphene　on　cement　particles.　Our　proposed　method　is　approximately　80%　less　expensive　than　commercial　techniques.　Evaluation　of　the　microscopic　morphology　demonstrated　uniform　distribution　of　graphene　in　the　cement　matrix,　which　improved　the　mechanical　properties　of　the　cement　paste.　The　compressive　strengths　of　the　test　groups　with　3%　carbon　source　improved　by　almostly　38%　and　48.9%,　respectively,　compared　with　pure　cement　paste.　This　newly　established　technique　is　essential　for　the　future　design　of　excellent　graphene-based　cement　materials　and　the　achievement　of　multifunctional　cementitious　applications.　©　2023,　The　Author(s).
