Effect of High-Velocity Impact Loading on Concrete Slabs Reinforced by Metallic Strips from Soft Drink Cans as Fiber

The idea of enhancing concrete slabs' ability to resist impact has been discussed in this study and, specifically, the use of soft drink can strips fibers (SDCSF). Concrete structures are classified as brittle material when happen to be exposed to impact loads like the firing of guns. Some of the past research works revealed that subjected to impact loads, the concrete structures disintegrated into several pieces. And because of the brittleness, fibers are incorporated into concrete at various ratios of 0. 5%, 1%, and 1.5% mean weight of cement and various proportions of 3cm, 6cm, and 9 cm to enhance concrete’s resistance. Squire slab specimens with the dimension of (500 mm × 500 mm) and thickness of 50 mm. Ten specimens were subjected to high-velocity impact load by gunfire from a weapon M16, bullet diameter 7.62 mm, from a distance of 15 m. The arrangement used was to impact a single point (one bullet) at the centre of each panel. The research found that using such a type of fiber with different percentages and lengths could increase the resistance impact load. Moreover, the results showed that reducing the spalling area, the scabbing area, and reducing the redial crack length. It can be concluded that the spalling area of specimens with 1.5% soft drink can strips and 9 cm length at 28 days decreased by 21.48% compared to the reference sample (R). The scanning area of specimens with 1.5% soft drink can strips and 9cm length at 28 days was decreased by 24.72% compared to the reference sample (R). The redial crack length of specimens with 1.5% soft drink can strips and 9cm length at 28 days was decreased by 29.32% compared to the reference sample (R).
