The document describes an experimental study on constructing bubble deck slabs by inserting coconut shells. It aims to determine the load bearing capacity of filler slabs using coconut shells and compare it to conventional slabs. The study also aims to estimate the amount of concrete saved by using coconut shell fillers and to compare the strengths of conventional and filler slabs. It outlines the objectives, scope, literature review on previous similar studies, materials used including coconut shells and concrete mix design, and the methodology to be followed for casting specimens and conducting experimental testing and analysis.
