Abstract: The main objective of this Thesis is study the effect of adding polymers to concrete on the behavior of R.C. beams exposed to fire under loading on the behavior of reinforced concrete (RC) beams under different fire and cooling conditions. Experimental Work includes eighteen beams were tested with rectangular section its dimensions (120 * 250 * 1650) mm, divided into six groups, using different polymer ratio (RP) equal to (0%, 5%, and 10%) from cement weight. First and second groups were tested at room temperature. The third and fourth groups were loaded by 30% of the load measured at room temperature and then subjected to a temperature of 700° C for one hour then the load was increased up to failure. The fifth and sixth groups were loaded by 30% of the load measured at room temperature and then subjected to a temperature of 700 ° C for one hour then cooling by water then the load was increased up to failure. Analysis of test results shows clear improve in Flexural and shear Strength by adding polymer for the R.C beams not exposed to fire. But in the R.C beams exposed to fire the Flexural and shear Strength decreased by adding polymer.
Keywords: RP; temperature; Flexural and shear Strength.
