Abstract: A diluent-free curable epoxy resin composition for preparing a composite comprising: (A) at least one epoxy resin composition comprising a blend of: (A1) at least one epoxy resin, and (A2) at least one divinylarene dioxide; and (B) at least one hardener composition; and (C) at least one reinforcement materials; wherein the viscosity of the curable composition is the range of from about 0.15 Pa-s to about 1.5 Pa-s; and wherein the curable composition is adapted for providing a cured composite product made from the curable composition such that the composition being cured provides a cured composite product having an increased Tg of greater than about 5° C. as compared to a curable composition having a reactive diluent.

Abstract: Non-invasive moisture-sensing within concrete (such as concrete buildings, bridges, etc.) or a polymeric material may be accomplished by a capacitor structure comprising a porous material built inside the concrete or polymeric material. The capacitance measurements change based on the amount of moisture in the porous material. Moisture-sensing can be monitored remotely (including for submerged and other structures), relatively non-invasively, and in a repeatable and reversible fashion without intermediate conditioning or resting.
