Designing the slabs using steel fibre reinforced concrete

What is it about?

Cutting and placing steel bars in concrete slab is a time consuming process. However, the use of small discrete steel fibres in the concrete, added at the time of mixing, makes the casting of slabs more simple and saves a lot of time that otherwise goes into the reinforcement cutting and its placement, and simultaneously, improving the strength and durable characteristics of the concrete slabs. The paper presents the design process to proportion the slabs using steel fibre reinforced concrete and its response under external load

Why is it important?

It is proved that the conventional steel bars in the concrete slabs can be totally replaced by using a properly designed steel fibre reinforced concrete mix. The slab so constructed exhibits a better structural behaviour in terms of the crack width, load-deflection response and the corrosion resistance in comparison to the conventional RC slabs; thereby making the slab more durable almost at the same overall cost.
