POLYMER CONCRETE PREPARED FROM AN MMA-STYRENE COPOLYMER SYSTEM

Polymer concrete is a premixed material that is prepared from portland cement, aggregate, and polymer such as methyl methacrylate (MMA) or styrene or a combination of the two. A polymer is used as the main binder in the material matrix. Experiments were conducted to investigate the effect of using different copolymer ratios of MMA and styrene and the effect of polymer loading on the strength of the material. Mortar specimens with thermal curing process at 158 F (70 C) were prepared for the test program. Test results indicated that a 50:50 copolymer system of MMA and styrene gave much higher strength than the system containing MMA or styrene alone. Results also showed that the strength of the composite increased as polymer loading up to 12 percent (wt) increased; the strength decreased for higher polymer loading. Less polymer loading was required for polymer concrete containing coarse aggregate. A series of polymer concrete with 9 percent (wt) copolymer of 50:50 MMA and styrene was prepared. Tests including compression, tension, bending, double shear, water absorption, and chemical resistance (18 percent hydrochloric acid) were conducted, and results compared favorably with those for conventional concrete. Moreover, the polymer concrete appeared to have the same type of physical properties as the polymer- impregnated concrete.
