Abstract: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.
