Abstract
Concrete plays a major role in the field of construction as the use of concrete is high in the construction industry. Slab is an essential part of structure and it has to be designed properly. Concrete slab use more concrete than required and hence it needs to be optimized. One of the methods to reduce quantity of concrete in slabs is by providing voids in the tension zone. In the present paper, experimental and analytical study has been performed to compare the flexural strength of the normal slab and voided slab. For analytical study, ANSYS 18.1 software has been used. The slab specimens were of dimension 500 × 500 × 90/100/110 mm with similar boundary condition. The diameter of voids has been taken as 55 mm and 40 mm with a spacing of 25 mm between each void. The aim of this paper is to discuss and compare flexure behavior of normal slab and voided slab and reduction in weight of the slab by void formation.
