Abstract: A concrete product set by pouring a concrete slurry which includes a concrete mixture; a lithium-coated colloidal silica admixture; and optionally, 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 concrete product defines capillary structures that at least in part fill with lithium-coated silica and lime. In another exemplary embodiment, wherein optional graphene oxide is used in the concrete slurry, the surrounding aggregate and cement is embedded with graphene oxide flakes. In another exemplary embodiment, the present invention is directed to a process for placing a jointless and/or fiberless slab. The process includes the steps of preparing a concrete slurry; pouring the concrete slurry onto substrate; and allowing the concrete slurry to cure. In another exemplary embodiment, the present invention is directed to the product itself.
