M-Grafe Concrete Additives contain a form of graphene Nano platelets. Graphene Nano platelets are particles consisting of multiple layers of graphene. This Nano-material was selected for the unique and performance-enhancing characteristics it provides to concrete. During the formation and curing of cement, these tiny micro-platelets are able totake up space previously filled by air. Less air means higher density and higher density is directly related to performance improvements in flexural strength, abrasion resistance, impact strength and toughness.
