الملخص

This research includes the study improvement of the mechanicalproperties and resistance to high temperatures of concrete using steelfibers with different ratios of volume (0.5%, 1%, 1.5%) and polymer withdifferent weight ratios of polymer to cement (3%, 7%, 10%).The samples were made as follows: (100, 100, 100mm) cubes forcompressive strength tests, (100, 200mm) cylinders for splitting tensilestrength tests and (100, 100, 500mm) prisms for flexural strength tests.The results show an improvement in all properties of steel fiberconcrete with and without polymer as compared with referenceconcrete. In compressive strength, the increase was (14.2% - 40.6%) forsteel fiber concrete, while the increase was (44.8% - 86.64%) for steelfiber concrete containing polymer. In splitting tensile strength, theincrease was (50% - 91%) for steel fiber concrete, while the increase was(102.4% - 124.7%) for steel fiber concrete containing polymer. Forflexural strength, the increase was (24.2% - 48.3%) for steel fiberconcrete, while the increase was (62% - 78%) for steel fiber concretecontaining polymer.As concerns the effect of temperature on concrete tests, steelfiber concrete containing polymer gained compressive, tensile, andflexural strength greater than reference concrete specimens for alltemperatures (100, 300, 500, 700Cْ ). The increase in compressivestrength was (82%, 54%, 69.8%, 171.4%), respectively; while theincrease in tensile strength was ( 119.2%, 132.6%, 99%, 52.3%),respectively; and the increase in flexural strength was( 87.3%, 194.4%, 115.8%, 164%), respectively.
