    Abstract: This study was conducted with an aim to analyze the spatial variability of soil properties with depth under cement dust pollution areas. In soil there is nutrient variation in different depths, the variations can also affected by the anthropogenic factors. In this study, the nutrient variation between soil depths (0-20cm & 20-40cm) in cement dust p... Show More

    Abstract: Today we are more concern about the environment. Synthetic polymers are the most responsible pollutant for environmental pollution. Good replacing agents for the synthetic polymers are the natural polymer. That is why the uses of natural fiber reinforced composites are increasing day-by-day. In this research natural polymer coir fiber was used as t... Show More
