Determination of mechanical and thermal properties of insulating raffia leaves particleboard made with tannic powder of african locust been pod shell (parkia biglobosa)

Sustainable development finds its full meaning in the sense that it promotes the use of renewable resources, available in sufficient quantity to meet the diverse needs of a society in the present and in the future. This concept includes social, economic and environmental factors which must all be taken into account because they are decisive in the absolute availability of the resource. The cob is the part of the maize which bears its seeds and which, after shelling, is thrown away as vegetable waste. Corn is a food grain of the Gramineae family, whose tight kernels on a long cob are rich in sugar and gluten. This plant grown in Africa and around the world whose use of its different parts is varied. Corn was probably domesticated in southern or central Mexico. In recent years and in the context of the need to use renewable resources, the use of locally available raw materials has literally exploded, particularly in the field of construction. At the origin of the research, we find first of all the desire to valorize the corn cob. It is dried and then reduced to a powder whose particle size is determined before use.It is also a question of appreciating the mechanical and thermal properties of the Compressed Earth Block (BTC) with the reinforcement of vegetable fiber by valuing the cob of corn which is a biodegradable natural product as reinforcement in the manufacture of the ecological BTC which meets the standards. international. The composite material obtained was characterized mechanically and thermally. The mechanical properties comply with the values of the standards in force. Similarly, the results show that thermal conductivity and diffusivity decrease with the introduction of corn cob flour while effusivity increases. This particleboard could be used for thermal isolation
