The present invention relates to compositions and methods for reducing or preventing the loss of drilling fluids and other well servicing fluids into a subterranean formation during drilling or construction of boreholes in said formation. Specifically, this invention comprises a curable thermosetting composition comprising a polyfunctional (meth)acrylate, a polyfunctional (meth)acrylamide, or mixture thereof, one or more epoxy resin, and one or more (cyclo)aliphatic polyamine.

An aggregate includes a polymeric foam present in a range of about 80 vol % to about 85 vol % of the aggregate. A cementitious matrix is present in a range of about 10 vol % to about 13 vol % of the aggregate. One or more resins are present in an amount of less than about 2 vol % of the aggregate, and one or more reinforcing fibers are present in an amount of less than about 1 vol % of the aggregate.
