Abstract :

This paper focuses on the extent of variation in permeability and surface area of soils when particle size distribution (psd) of the soils changes. Particle size distribution is the distribution of the weight or volume of solid particles falling into different size ranges. Two different soil samples were collected as sample A and sample B and the distribution of their particle sizes were determined. Ethylene glucol was used as an adsorbate in the determination of the surface area of the soils in the two samples. Falling head and constant head permeability tests were used to determine the permeability of the soil samples respectively. The results obtained in this study have corroborated the theories in soil mechanics that say the more the amount of fines in a soil the larger the surface area and the smaller the permeability of the soil.
