Abstract: The invention relates to a method for the refurbishment of porous construction materials said method comprising the steps of - mixing water and a composition C, said composition C comprising, a) 100 mass parts of Portland Cement, b) 1 – 18 mass parts, preferably 1 – 10 mass parts, more preferably 1 – 7.5 mass parts, still more preferably 1 – 6 mass parts, especially 1 - 5 mass parts of calcined clay, c) optionally 10 - 250 mass parts of aggregates, - applying the mixture thus obtained to a porous construction material, and - optionally hardening the applied mixture. The invention also relates to a composition comprising Portland cement, calcined clay, and optionally aggregate to be used in a method for the refurbishment of porous construction materials.

Abstract: A concrete product set by pouring a concrete slurry includes (a) a concrete mixture; (b) a graphene admixture (102); and (c) at least one reinforcing fiber selected from the group of fibers (24). As the poured concrete slurry cures, the poured slurry hardens into a composite material product, and the composite material is embedded with graphene. In another exemplary embodiment, the present invention is directed to a process for preparing a concrete product (800). The process comprises the steps of (a) preparing a concrete slurry with integral graphene (402); (b) pouring the concrete slurry (404); (c) allowing the concrete slurry to cure (406); and (d) optionally spray-applying graphene (408) and/or optional colloidal silica (402) as a curing technique. In another exemplary embodiment, the present invention is directed to the product itself; namely, a concrete product with fibers and embedded graphene.
