Polymer Impregnated Concrete: Field Studies
The principles developed in the laboratory for polymer impregnation of concrete to depths below the top layer of steel reinforcing rods were applied to the impregnation of large concrete slabs and a bridge deck. These principles include drying of the concrete to the desired depth of impregnation, allowing sufficient time for complete impregnation with monomer (e.g., using pressure to increase the rate of penetration), and selecting the monomer, not only for its cost and the properties of its polymer, but also for its rate and uniformity of penetration. The polymer-impregnated slabs show increased compressive and split-tensile strengths, decreased water absorption, and improved resistance to corrosion, freeze-thaw cycling, abrasion, and acid-etching. The polymer-impregnated bridge deck shows decreased water absorption and improved resistance to acid-etching. These improvements give promise of exceptional durability in practice.
