“…2 Salt loading in grout is limited because large amounts of salt prevent setting and lead to poor leaching control. 1,3,4 Previous works have focused on developing "polycerams", or organic-inorganic hybrid materials for use as waste forms. 5,6 Polycerams incorporate a ceramic or oxide component into the polymeric matrix, where the scale, structure, and connectivity of the inorganic phase may vary over a wide range, resulting in significant improvements in mechanical and chemical properties, depending upon the level of connectivity between the inorganic and organic components.…”
