Process for impregnating a concrete or cement body with a polymeric material
This patent describes a method of making a cementitious solid body which is resistant to penetration by water. It comprises: forming a curable viscous slurry by mixing together organic-soluble solids which are substantially insoluble in water and a grout comprising a powdered cement and an aqueous component; solidifying the slurry by curing the grout, thereby forming a solid mass containing a dispersion of organic soluble solids; contacting the resulting cured body with an organic solvent for the organic-soluble solids, the solvent comprising a polymerizable monomer and a polymerizing catalyst for the monomer, whereby the solvent dissolves at least a portion of the dispersed organic-soluble solids and is distributed within the solid mass; and curing the polymerizable monomer to form a solid body resistant to penetration by water.
