The Behavior of Reinforced Concrete Beams with Coconut Shell as Coarse Aggregates CIVIL Project aims at analyzing flexural and compressive strength characteristics of concrete produced using crushed, granular coconut as substitutes for conventional coarse aggregate with partial replacement using M30 grade concrete. Beams are casted, tested and their physical and mechanical properties are
After removing the coconut, the shells are normally disposed as waste. Large numbers of disposed coconut shells are yet to be used for any commercial purpose hence incorporating it in concrete as a construction material with respect to other lightweight aggregates is an awesome topic to further look into.

Control mix (M1) that is, without CS was made. Coarse aggregate was then replaced with CS in 10 (M2), 15 (M3), 20 (M4) percentages to study effect of CS replacement.
201788&ensp·&enspThe properties of coconut shells are compared with those of conventional coarse aggregates to find the suitability of coconut shells as a replacement of coarse aggregates of concrete. Several conclusions can be drawn from the present work. Coconut shells have high toughness and abrasion resistant properties.
It also paved the way to the recognition of using coconut shells and fiber as a substitute for aggregates in developing concrete hollow blocks. As a whole, the study' main concern is the environment and the construction and building technology to enhance natural world as well as building materials.
