ABSTRACT
Housing all over the world majorly comprises of concrete structures. They provide isolation and thermal comfort to the occupants. Majority of the concrete structures have flooring/roofing of thick concrete to bear the design loads. Due to his, the complete volume (eliminating the negligible volume of the reinforcement) of the roof slab comprises of concrete. Due to this, production of concrete has increased. Concrete production is not environment friendly. It is the primary producer of Carbon dioxide. In addition to this, the problem of concrete waste is at rise. Concrete waste can be reduced by two ways: recycling and using efficient volumes. Recycling is using the concrete waste in concrete generation which is of course of lower quality. Efficient volume is the way of using concrete in the most efficient way possible by substituting materials. In this paper, polyethylene balls are used in the slab to reduce concrete volume while maintaining the structural properties of the concrete. A comparison of strength of slab with the polyethylene balls and without them has been done to show the effectiveness of the new method. Various other strength tests were carried out and have been tabulated. At the end, cost effectiveness of the proposed slab has also been given.
Key words: Bubble deck slab, polyethylene balls, recycling concrete, concrete slabs systems.
