Aggregates – Fine aggregate “Fine aggregate” are the aggregates whose size is less than 4.75 mm. Example: Sand is used as fine aggregate in the preparation of concrete and cement mortar. For increased workability and for economy as reflected by use of less cement, the fine aggregate should have a rounded shape.

Sand dunes in desert areas are transported by wind. They can be used for certain construction purposes. • Fine-grained soils (silts and clays) can also be transported by wind, specially silts (because clays posses cohesion or bond which reduces wind erosion). The fine-grained soils transported by wind are termed “ loess ”.
