DEVELOPMENT OF POLYMER CONCRETE AS A HIGHWAY PATCHING MATERIAL
A study has been conducted on the preparation and properties of polymer-concrete using polystyrene and/or poly(methyl methacrylate) as the polymeric component in the concrete composites formed. Both thermal and catalyzed polymerization methods were used to transform monomer-polymer mixtures into the polymeric component of polymer-concrete. Catalyst promoters were used to develop room-temperature polymerization systems which developed full strength within two hours. The effect of aggregates (silica sand, brown sand, gravel and limestone) on the physical properties of polymer-concrete compositions was also studied. In general, it was found that systems involving methyl methacrylate produced the best properties. Combinations containing from 9 to 15% of the polymer were studied, all gave higher compression, tensile, flexural and bonding strength than the corresponding control samples prepared without polymer. Abrasion resistance, water absorption, acid resistance and freeze-thaw durability were greatly improved with the use of either polymer system.
