ABSTRACT:
A process for drying concrete to the appropriate moisture content for proper impregnation of the concrete with a polymer or a monomer for in situ polymerization. This is accomplished by heating the concrete until its temperature at the desired depth of polymer penetration is at least about 230.degree. F. In another embodiment of the invention the dried concrete is impregnated with a monomer composition capable of polymerization and is polymerized within the concrete.
