Özet
Açıklama
Behaviors of the flat plate-column assembly of four reinforced slabs are investigated. Polypropylene synthetic fibers are added to the dense concrete that includes 63% of fine aggregate, the dimensions of the tested square slabs were 500 × 500 × 60 mm, reinforced by constant reinforcement ratio of 0.9%. The main parameter was the polypropylene volume fraction, where the percentages of fibers are used (0.5, 1.0, and 1.5%), compared to normal concrete slabs. The test results show that adding fibers to the dense concrete are control the slab deformation, moreover, adding 1.5% of fibers was increasing the ultimate resisting load by 39%, and increasing the energy absorption capacity by 149%.
