TL;DR: In this article, the authors presented the potential of a bentonite-limephosphogypsum mix reinforced with sisal fiber in effectively reducing the pavement thickness in an extremely problematic sub-soil condition intended for road construction.
Abstract: The paper presents the potential of bentonite-limephosphogypsum mix reinforced with sisal fibre in effectively reducing the pavement thickness in an extremely problematic sub-soil condition intended for road construction. In view of which, compaction, unconfined compressive strength and California bearing ratio tests were conducted. The content of lime, phosphogypsum and sisal fibre was varied from 0 to 10%, 0 to 10% and 0 to 2% respectively. The specimens were prepared at their respective optimum moisture content and maximum dry unit weight for conducting the unconfined compressive strength and bearing ratio tests and were cured for 3 to 28 days. The results of this study reveal that the unconfined compressive strength and bearing ratio of the bentonite-lime-phosphogypsum mix increased with the increase in curing period. Addition of sisal fibres to the bentonite-limephosphogypsum mix changes the behaviour of the composite from brittle to ductile in the post peak region. Scanning electron micrographs and energy-dispersive X-ray analysis confirms the improvement in unconfined compressive strength and bearing ratio. The improved behaviour of the composite indicates that the sisal fibres have the potential for use in road pavements.

TL;DR: In this paper, the development and electrical characterization of sisal powder-filled polyvinyl alcohol (PVA) composites is reported, and the effects of temperature and frequency variation on dielectric constant (e' and dissipation factor (tan δ) and on a.c. conductivity (σa.c.) were determined.
Abstract: In this paper, development and electrical characterization of sisal powder filled polyvinyl alcohol (PVA) composites is reported. Dielectric measurements were conducted on these composites on a LCR meter in the temperature range from 30 to 150 °C and in the frequency range 1 kHz - 10 kHz. The effects of temperature and frequency variation on dielectric constant (e’), dielectric dissipation factor (tan δ) and on a. c. conductivity (σa.c.) were determined. On increasing the filler content, dielectric constant increased, it was mainly due to motion of the dipolar groups of the interfacial polarization occurring in the composites. The conductivity increased with rise in temperature. Keywords: PVA, Electrical Properties, Dielectric Properties, Electrical Conductivity

TL;DR: The result from the mechanical tests reveals that the fibre length of 3 mm and fibre weight percentage of 50, sisal fibre reinforced composite offers superior properties compared to other fibre lengths and weighting percentages of sisal fiber.
Abstract: The present study investigates the mechanical properties such as tensile, flexural and impact of randomly oriented short sisal fibre reinforced polyester composites. The composites were fabricated using compression moulding method with varying fibre length (3 mm, 4 mm, 5 mm) and varying weight percentages (20%, 30%, 40%, 50%) of fibre in room temperature. The result from the mechanical tests reveals that the fibre length of 3 mm and fibre weight percentage of 50, sisal fibre reinforced composite offers superior properties compared to other fibre lengths and weighting percentages of sisal fibre.

TL;DR: In this paper, a comparison of strength of pavement wearing coat made with SMA mix with fibre and without fibre was done, which evaluated the viability of sisal fibres as stabilising agent in the mixture.
Abstract: The technology of asphalt materials and mixtures is discovered and mostly used in Europe and North America. The SMA (stone matrix asphalt) mixture is a gap-graded mix. In this present study comparison of strength of pavement wearing coat made with SMA mix with fibre and without fibre was done. This research was done to evaluate the viability of sisal fibres as stabilising agent in the mixture by laboratory tests in which a flow parameter was analyzed, as well as the mechanical properties of the mixture. For the SMA mix the aggregate gradation was taken as per the MoRTH specification and the binder content was 4%, 4.5%. 5%, 5.5%, 6%, 6.5%, 7% by weight of aggregate and fibre used was 0.3% by weight of aggregate. Here we used cement as filler and 60/70 grade bitumen as binder.
