Size and morphological characteristic of fine aggregate play an important role to study the workability parameters of concrete and mortar. In this study, the morphological characteristics like angularity, roundness, sphericity and roughness were selected. The soil grains of different size of fine aggregate are examined using foldscope microscope. The parameters varied in the paper are the type of the soil, source of the soil and depth from which soil sample is taken. The soil samples are collected from the natural resources - River- sand, fertile soil, red soil clay, sea sand and artificial sources - M-Sand and P-Sand . From the image it is able to know the shape and texture of the sample and corresponding correction in the concrete mix design can be done to improve the fresh concrete properties.
