    What Is Bulking Of Sand Bulking Of Sand Is Caused Due To

    Image Credit www.gharpedia.com. Free moisture present in the atmosphere forms a thin film around each sand particle. This thin layer of moisture exerts surface tension which pushes the neighbouring particles away from each other. Therefore, due to this force no point contact is possible between the sand particles. This caused an increase in volume or bulking of sand.
