Abstract Sixteen groups of comprehensive tests have been conducted to investigate the modifications in the physical properties of a weak expansive soil due to the addition of a cement jute fiber. The tests have been conducted to analyze the liquid plastic limit, the particle distribution and the free expansion rate. The results show that: (1) With an increase in the cement-jute fiber content, the free expansion rate of the modified expansive soil gradually decreases, however, such a rate rebounds when the fiber content exceeds 0.5% and the cement content exceeds 6%. (2) With an increase in… More >

Abstract In order to mitigate the risks stemming from the utilization of mineral and synthetic organic substances, consensus exists in the literature that additional efforts should be devoted to the identification of adequate equivalent natural (ecological) materials. This work presents the outcomes of a preliminary study where the physical, mechanical, chemical and thermal properties of natural fibers have been considered. Initially, areca, and materials such as Moroccan doum and jute are considered. As a case study, a brake pad based on natural fibers is critically assessed. More >
