POLYMER CONCRETE REPAIR OF BRIDGE DECKS

Techniques for polymer concrete (PC) repair of concrete have been developed. PC has proven to be a strong, durable material that bonds well to sound concrete. The chemicals include monomers, promoters and initiators. The materials are volatile and flammable, but construction experience has shown that these materials can be safely used on large projects. Well graded, dry, clean aggregate is required as a filler. The preparation of the repair area is similar to the preparation required for other materials. The concrete surface must be sound, dry and clean to insure a good bond. Cracks and holes in concrete and formwork must be sealed to prevent monomer leakage. Monomer may be poured over aggregate which has been placed dry in the hole, or the monomer and aggregate may be premixed before placing. The material should be consolidated and finished by screeding and troweling. The surface should be kept covered until polymerization has occurred which requires an hour or less. Examples of thin, shallow, and full-depth PC repairs are given. The cost of chemicals averages about $260 per cu. yd ($340 per cu. m).
