The objective of this work is to evaluate the technological performance of adding açaí fibre (with additions of 1.5%, 3.0% and 5.0% relative to cement mass) in its natural condition and after surface treatment with NaOH in mortars based on cement and lime. To estimate the contribution of all major components to the thermal properties of natural hemp fiber bundles, the thermal decomposition of hemp fibers following several chemical treatments was studied by the differential thermogravimetric analysis (DTA/TGA). Coconut cultivation is concentrated in the tropical belts of Asia and East Africa (Aziz et al., 1984). This research is beneficial for the innovation of acoustic material for interior design and architecture. (1964). Tenacity and elongation-at-break decreased with chemical treatment and UV irradiation. The best results were obtained for mercerized fibers where the tensile strength was increased by about 53% as compared to the composites with untreated fibers, and about 33.3% as compared to the composites without fibers. The effects of geotextiles on runoff and soil erosion have been documented; however, the conditions studied to date have been limited and are insufficient for the optimization of the selection and application of geotextiles for other sites. Coconut fiber can provide good tensile strength due to the 46% lignin content in it aside from having more rotting resistance under wet conditions compared to teak wood, which only has 39% content of lignin. With adequate control of their preparation, they could be reused in the manufacture of mortars in the construction. This composite foam panels were fabricated by using polyurethane molded method. Results were compared with a control plot. X-ray and infrared spectral measurements revealed that a part of the noncellulosic components does occupy the intracellular space and plays a significant role on fine structural changes produced during the alkali treatment.
