Techniques for producing polymer-impregnated concrete (PIC) are evaluated and a processing cycle recommended. A study of concrete mix variation indicates that this parameter has only a small effect on the final strength of the composite. The impregnation of high-pressure stream-cured concrete produces PIC with strengths greater than those obtained from fog-cured material. Impregnation parameters such as vacuum, pressure, soaking time, and methods of encapsulation all have an effect on the strength of PIC. The degree of sample evacuation is one of the most important parameters. Complete saturation and therefore maximum improvement in strength and durability is accomplished only after prior evacuation to approximately 30 in. Hg (760 mm). The feasibility of using water as a means of reducing monomer losses due to evaporation and drainage has been demonstrated. Test data indicate that the underwater polymerization of methyl methacrylate has no detrimental effects on the properties of the composite and may even produce benefits due to the increased polymer content. /ACI/
