Residual strength capacity of reinforced reactive powder concrete two-way slabs subjected to drop weight

This paper presents an experimental investigation of the effect impact force on residual strength capacity simply supported reactive powder slabs. Eight specimens reinforced concrete slabs with dimensions 500 x mm and 70 in four categories were used. The influences slab compressive (conventional concrete), steel fiber proportion (1, 1.5, 2%), percentage reinforcement tension zone (ρ1=0.007, ρ2=0.011, ρ3=0.0179), number impacts (two impacts, six impacts) all investigated this test. Investigations carried out to ascertain each slab's response, including first cracking load, failure strain, maximum central deflection, crack pattern. results showed that using instead normal increased mechanical properties resulted a significant increase load. In addition, deflection strain increased. Increasing ratio load while simultaneously decreasing due improvement moment resistance. Furthermore, it was discovered through experiments addition mixture enhanced slab’s post-cracking reactivity. presence raised resistance by 21.63% as from 1% 2%. is because
