Abstract: This paper gives an audit of the use of coconut shells and coconut fiber in street development. Coconut shells and coconut fiber are new waste materials utilized in the sidewalk and parkway industry. A few investigations demonstrated that coconut fiber can build the soundness, slide obstruction and strong modulus while coconut shells can improve the aberrant rigidity and static wet blanket conduct of the changed black-top asphalt. Conversely, coconut fiber doesn't improve the exhaustion life of the altered bituminous blends. As a rule, the past research shows that coconut shell and coconut fiber essentially improves the building properties of blacktop blends when blended in with altered bitumen. The conventional mix practiced in the field was adopted for the production of coconut shell aggregate concrete paver blocks. For comparison purposes, conventional aggregate concrete paver blocks were produced and tested in parallel. Keywords: Powdered Coconut shell, fine aggregates, concrete.
1. INTRODUCTION One of the most critical problems in environmental protection and natural resource conservation is waste management. Different changes in the environment and an increase in population are one of the main causes of the many processes of deterioration which have altered the ecosystem of our own planet, together with the generation of municipal solid waste (MSW). Therefore, the importance of creating and reusing waste to create a greener and healthier place on earth is highly significant. Using coconut shells as a representative for using agricultural waste will be emphasized in this research. The idea of being renewable, low-cost, lightweight, having high specific strength and stiffness have made agricultural waste ideal for use as a construction material. Objective The main objective of the study is to investigate if using powdered coconut shell as a partial replacement for fine aggregates could meet the standard compressive strength of ACI for sidewalk pavement.
2. REVIEW OF RELATED LITERATURE The researchers’ study is based on the different literatures cited here. The goal of this study is to improve the cost effectiveness of construction materials by using recycled aggregate for sidewalks. And on how we can use waste material as a useful construction material such as sidewalk or footpath.
