A concrete product set by pouring a concrete slurry includes a) a concrete mixture; b) a graphene admixture; c) a colloidal silica admixture; and d) at least one reinforcing fiber selected from the group of fibers. As the poured concrete slurry cures, the poured slurry hardens into a composite material product, and the composite material defines capillary structures that at least in part fill with silica and lime, and the surrounding composite material is embedded with graphene. In another exemplary embodiment, the present invention is directed to a process for preparing a concrete product. The process comprises the steps of a) preparing a concrete slurry; b) pouring the concrete slurry; and c) allowing the concrete slurry to cure. In another exemplary embodiment, the present invention is directed to the product itself; namely, a concrete product with or without fibers, or to the admixture(s).
