AGRICULTURAL WASTE IN LOCAL BUILDING MATERIALS: COMPARATIVE STUDY
Abstract - The main objective of this study is to compare the performances of two basic materials, clay or laterite mixed with rice straw waste. This allowed us to propose properties of samples for building materials. Clay and laterite formations represent the most abundant materials resources in Africa. Agriculture is among the economic sectors that produce more waste. For rice straw waste, its high content of cellulose makes it difficult to digest. So, few animals can use it as food. Most of the straws are lost, buried, burned, or used as litter. The Interesting results obtained show that the integration of rice straw in building materialsimproves the thermal comfort and recycles the straw. Also, the comparison of performances of materials makes it possible to indicate ranges of properties that we can use in the construction of buildings.
