Design and Analysis of Filler Slab Using Terracotta Fillers

Abstract

In the gracefully developing industry of construction, the cost of the project plays an important role which is mainly acquired by the concrete. To reduce the quantity of concrete without compromising the strength of concrete, filler slab technology has been used. The primary idea behind employing filler-slab technology is to decrease the amount of concrete in the tension zone, as not all concrete in this zone contributes to the tensile properties. Instead, lightweight, inert, and inexpensive filler materials are utilized to replace this non-contributing concrete, without compromising the quality and structural stability of the building. In the design of a two-way slab, the filler material is positioned between the reinforcement spacing, ensuring adequate cover. Terracotta pots are used as filler materials. Both conventional slabs and filler slabs are analyzed using STAAD.Pro and a comparison is made between the filler slab and a standard slab of the same size. This research proves that filler slabs are cost-effective and structurally safe as compared to conventional slabs. Overall, filler slabs offer a cost-effective and sustainable alternative to traditional solid slab construction, with several benefits such as improved thermal insulation, aesthetic appearance, and reduced environmental impact.
