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 determined.
The main target area is to promote the use of these ‘seemingly’ waste products as construction materials in low-cost housing. It is also expected to serve the purpose of encouraging housing developers in investing these materials in house construction. The outcomes of an investigation carried out on the comparative cost analysis and strength characteristics of concrete produced using crushed, granular coconut and palm kernel shells as replace for conventional coarse aggregate.
The properties of concrete using coconut shell as coarse aggregate were investigated in an experimental study. Compressive, flexural, splitting tensile strengths, impact resistance and bond strength were measured and compared with the theoretical values as recommended by the standards. For the selected mix, two different water–cement ratios have been considered to study the effect on the flexural and splitting tensile strengths and impact resistance of coconut shell concrete. The bond properties were determined through pull-out test. Coconut shell concrete can be classified under structural lightweight concrete. The results showed that the experimental bond strength of coconut shell concrete is much higher than the bond strength..After studying the strength/economy ratio, it was Decide that coconut shells were more suitable than palm kernel shells when used as replace for conventional aggregates in concrete production.
The experimental Behavior of Reinforced Concrete Beams with Coconut Shell as Coarse Aggregates results of four beams, two each in CS and the NWC. The comparison of mechanical properties and structural behaviour of the NWC and CS beams. The crack width, deflection, ultimate strength, concrete and steel strains are analyzed and compared for both beams. Based on the results, the following conclusions may be drawn: The overall flexural behaviour of reinforced PKSC beams used in this study closely resembles that of equivalent beam made with NWC are presented in this project report.
