An Experimental Investigation On Bubble Deck Slab

Abstract

For Decades, Several Attempts Have Been Made To Create Biaxial Slabs With Hollow Cavities In Order To Reduce The Weight. Bubble Deck Slab Is A Method Of Virtually Eliminating All Concrete From The Tension Zone Of A Slab, Which Is Not Performing Any Structural Function, Thereby Dramatically Reducing Structural Dead Weight. Polypropylene Hollow Spheres Replace The In-effective Concrete In The Centre Of The Slab, Thus Decreasing The Dead Weight And Increasing The Efficiency Of The Floor. By Introducing The Gaps, It Leads To 30 To 50% Lighter Slab Which Reduces The Loads On The Columns, Walls And Foundations, And Of Course Of The Entire Building. This Paper Is To Discuss About The Various Properties Of Bubble Deck Slab.
