Abstract
In world wide the ever increasing population in most developing countries and the corresponding increase in demands and need for infrastructural development, there is an urgent need to focus attention on low-cost alternative construction materials. Lignocellulosic fibers from green coconut fruit were dried under suitable conditions. After this, mixture of phenol cardanol formaldehyde resin and hardener are added to the fiber for binding purpose. Then it is impacted and compressed between two corrugated sheets, in order to obtain the shape of the roofing sheets, for 12 hours. After 12 hours of drying, it is then subjected to various tests such as tensile test, flexural test, impact test, compression test, and hardness test. The results are tabulated in order to compare it with GI sheet and asbestos cement sheet. This coconut coir roof sheet can be replace the former roofing sheets because of its durability, high strength, heat resistivity and low cost which i have been collected data from literature survey. The choose of this alternative is based on economic interest because it is very cheap, available with good mechanical properties, and also based on environmental interest because it is eco friendly. Thus this review paper addresses the characterization and performance of the coconut coir roofing sheet.
