The present invention relates to a composition in the form of a mixture comprising F-type fly ash, a reactive silicon source, a setting accelerator and a light aggregate with a density of less than 900 kg/m.sup.3 and a mechanical strength of at least 0.08 MPa, and the uses thereof to obtain light and fireproof construction materials.

A method of controlled hydration expansion of a smectite-containing day mineral (SCM) within an aqueous environment in a confined volumetric space, the method comprising the steps of: —introducing an amount of an SCM into said volumetric space via an inlet thereinto, and initiating the hydration expansion of the SCM to release SCM particles into the confined volumetric space, and increase the pressure therein; and —introducing a flow path modification to control said released SCM particles from undergoing a recompression, said modification thereby maintaining the pressure in the volumetric space.

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).
