A method for making concrete and concrete structures includes: providing a liquid admixture with a carbon nanomaterial in a liquid aqueous or organic solvent/compound mixture, mixing the liquid admixture with cement and water in a dosage selected to form a concrete mix having a carbon nanomaterial structure having individual carbon nanomaterial particles with a unit cell overlap, and hardening the concrete mix to form a concrete matrix with the carbon nanomaterial forming a 3-dimensional carbon nanomaterial network incorporated into the concrete matrix. The 3-dimensional carbon nanomaterial network has a shielding effect against high frequency electromagnetic pulses and other radiofrequency signals.

Described herein is a process for paving a surface with an asphalt paving material, comprising the steps of laying asphalt paving material on a surface to be paved; and combining an asphalt rejuvenator and the asphalt paving material; wherein the asphalt rejuvenator and the asphalt paving material are combined immediately before, concurrently with, or immediately after the asphalt paving material is laid on the surface to be paved. The asphalt paving material may be virgin asphalt, or it may comprise reclaimed asphalt pavement and/or recycled asphalt shingles.

Disclosed are: damage-resistant ECMCs that need to work and remain elastic between minus 120° C. and positive 300° C.; ECMCs that need to be able to contain a flame of 1900° C. for more than 90 minutes; and composite structures, especially highly stressed structures. One of the characteristic problems of ceramic matrices is their fragility. Indeed, when a fracture starts, it propagates easily in the matrix. Disclosed are elastic ceramic matrix composites (ECMCs), for which: the ceramic matrix is split into solid “ceramic microdomains” (CMDs); the CMDs are connected to one another by a dense network of “elastic microelements” (EMEs); and the bonds between the EMEs and the CMDs are strong chemical bonds, preferably covalent.

The present invention relates to a composition for a single-paste type hydraulic endodontic filling material comprising dimethyl sulfoxide (DMSO). According to one aspect of the invention, there is provided a single-paste type hydraulic endodontic filling composition, comprising a calcium silicate component and DMSO.
