Impact resistance of hybrid steel fiber reinforced concrete
The use of more than one sort of metals in a feasible composite could affect not just the overall concrete's characteristics, but also the cooperative synergy. With this objective in sight, an impact test for two hybrid steel fibre reinforced concrete (with hooked ends) is been conducted and de...

| description | The use of more than one sort of metals in a feasible composite could affect not just the overall concrete's characteristics, but also the cooperative synergy. With this objective in sight, an impact test for two hybrid steel fibre reinforced concrete (with hooked ends) is been conducted and described in this manuscript. Statistical analysis is additionally carried out to verify that the testing findings were viable. The drop weight test is the focus of this paper. Steel fibres with hooked ends have a unified diameter of 1mm and lengths of 30 mm and 60 mm are used during the experimentation. After 28 days, the initial impact energy for 1.5% concrete with Long steel fibre and Short steel fibre was 224.25 kN-mm. The least impact strength is achieved with a 0.5% volume fraction of 100% 30 mm Long steel fibre, while the highest impact strength is achieved with a 1.5% volume fraction of 25% 30 mm longer +75% 60 mm longer fibres. A blending of 25% 30 mm + 75% 60 mm steel fibre at a volume fraction of 1.5% has a maximum compressive strength gain of 42.98%, a flexural strength gain of 61.38%, a splitting tensile strength increase of 103.93%, and a static modulus of elasticity increase of 28.15% over plain concrete for 7 days of curing. HSFRC has enhanced durability and higher static mechanical properties due to the mutual effect of short and long steel fibres. |
