Abstract:
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.
