Graphene-based　materials　have　been　recently　adopted　to　improve　the　mechanical　properties　of　cement-based　materials.　However,　most　of　the　current　available　methods　show　poor　dispersion　and　high　cost.　The　development　of　a　cost-effective　graphene-based　cement　material　with　uniform　dispersion　of　graphene　in　the　cement　matrix　remains　challenging.　In　the　present　study,　glucose　is　used　as　a　low-cost　carbon　source　to　promote　the　in-situ　growth　of　graphene　in　the　cement　material.　The　proposed　method　for　the　development　of　in-situ　growth　graphene　on　cement　particles　costs　around　14%　of　the　commercial　ones.　Further　characterization　of　microscopic　morphology　and　structure　reveals　that　graphene　is　uniformly　dispersed　in　the　cement　matrix,　which　benefits　to　promote　hydration　process,　form　denser　microstructure　and　enhances　the　mechanical　properties　of　cement　paste.　Compared　to　the　pure　cement　paste,　the　compressive　and　flexural　strength　of　the　test　groups　with　3%　carbon　source　increased　by　38%　and　48.9%,　respectively.　The　developed　new　strategy　is　crucial　to　the　rational　design　of　superior　graphene-based　cement　material　and　achieve　multifunctional　applications　of　cementitious　materials.　©　2022
