| Abstract | ||||
| The objective of this research work is to study the absorption and dehydration behavior of some clay-sandy plasters reinforced with natural fibers that could be used for straw bale buildings. The plaster materials consisted of soil, sand and chopped straw. Straw is used as a reinforcement fiber for plaster. Three different types of fibers were used; wheat straw, barley straw and sawdust. The dehydration behavior of plaster materials were tested at three different temperatures, 30, 50 and 70°C. The obtained results showed that, the plaster reinforced with fibers dried slower than that without fibers. However, faster drying caused in cracks of the plaster which is not desirable in building surface coating. The moisture absorption rate increased with increasing fibers content and decreased with increased sand content. Moreover, the highest rate of moisture absorption occurred with the plaster reinforced with sawdust. While, the lowest rate of moisture absorption was achieved with the plaster without reinforcement fibers. | ||||
