Gypsum panels and methods for their manufacture are provided herein. The gypsum panels include a gypsum core having a first surface and a second opposed surface and a first fiberglass mat associated with the first surface of the gypsum core, such that gypsum from the gypsum core penetrates at least a portion of the first fiberglass mat.

A method of servicing a wellbore penetrating a subterranean formation, comprising placing into the wellbore a cementitious composition comprising a crosslinked polymeric microgel, a clay, a cementitious material, and water. By incorporating the crosslinked polymeric microgel and the clay as disclosed herein, the cementitious composition can be used at relatively high temperatures.
