Abstract:
SP-89 A collection of 17 papers dealing exclusively with the various effects of polymers in concrete, this book provides an extensive source of reference material. Presents advances in research, development, and uses of polymers. Case studies cover the effect of moisture on the physical and durability properties of methyl methacrylate polymer concrete; machine application of polymer concrete for highway repairs, commercial applications of epoxies in construction, and polymer concrete for bridge rehabilitation.

It has been reported by Dr. D. Fowler and others that the presence of water in a polymer concrete mix containing methyl methacrylate monomer reduces the mechanical strength of the composite. With coarse aggregate containing 3 weight percent moisture or higher reduces the compressive strength of a polymer concrete composite by 50 percent or more. This study was undertaken to determine the influence of moisture in the coarse aggregate on the strength and durability of polymer concrete made with a prepackaged two-component methyl methacrylate system developed at Brookhaven National Laboratory for the Federal Highway Administration. The data generated indicates that the compressive strength of “Fabucre te” polymer concrete composites do decay when water saturated coarse aggregates are used. In addition it was found that the use of some silane coupling agents can be used in the polymer concrete composite used in this study to obtain somewhat higher compressive strengths when water saturated coarse aggre-gates are used.

Conventionally reinforced concrete beams and polymer portland cement reinforced concrete beams were loaded to ultimate to determine the flexural behaviour. Two-point symmetrical loads were applied. Load-deflection and moment-curvature curves were predicted and compared with the observed ones. Reasonable agreement has been found. Polymer portland cement concrete beams were capable of utilizing higher percentages of reinforcement as compared to the same size ordinary beams. A P.P.C.C. beam developed 27% higher ultimate load, 46% greater deflection, and twice ductility. The maximum concrete flexural compressive strain,E CU for P.P.C.C. beam was higher than that of a companion control beam, and in general, it was found that plastic properties of P.P.C.C. beams are better than those of control beams. The maximum crack widths in P.P.C.C. beams were larger than in control beams, but the number of cracks in P.P.C.C. beams is less than that in ordinary beams.

Almost every structure where concrete or steel are used is vulnerable to the corrosive effects of chemical and environmental attack, as well as me-chanical abuse due to stress and vehicular traffic. Severe deterioration of such structures can result in the commercial, industrial and transportation areas. Epoxy resin based polymer products are used for the rehabilitation, repair and protection of both existing or newly constructed structures.

P.C. (MMA) systems have been in use for over 20 years and have become one of the most promising materials for the rapid repair of concrete, especially bridge deck repairs. The major bridge applications include joint and spa11 repairs, thin bonded overlays, and deck impregnation. The latest design concept utilizing P.C. (MMA) is for modular bridge deck replacement using the P.C. (MMA) for bearing pads, for joining individual panels and for contraction joint pours. Pre-packaged systems consist of two components, a pre-mixed powder that contains fine aggregates coated with polymers, initiators and pigments and a liquid monomer component (Methyl Methacrylate). The practical success of the systems have been due to the application technology developed through applied research by commercial firms. Repair work with P.C.(MMA) is similar to work using Portland Cement Concrete and proper surface preparation is essential to the successful use of P.C. (MMA) for rehabilitation. P.C. (MMA), has many advantages over conventional concrete, including among others, rapid setting, ease of use, usability in hot and cold temperatures and water and salt resistance. P.C. (MMA) can also be feathered to "zero". There are several different P.C. (MMA) systems, each ideally suited for a particular application (i.e. thin overlays, spa11 repairs, etc.) and any questions related to its use should always be checked with the manufac-turer.
