According to the standard classification of uniform soil, sand is divided into two categories: fine sand and coarse sand. Solid soil particles are called sand if their diameter is between 0.50 and 2 mm. Sand is in very commonly use in construction, often providing bulk, strength and stability to other construction materials such as asphalt, concrete, mortar, render, cement, and screed.

Located on Bubiyan Island in northern Kuwait, Bubiyan Port is a strategic deep-water port project that is under development. Once completed, it is expected to become a major transshipment hub in the region, connecting Kuwait to global trade routes. The port will have advanced container handling facilities and industrial zones.

Sand is produced by crushing rocks. Coarse stones are produced from the crushing and separation of natural stones, and finer sands, in addition to stones, also contain shells and corals. In civil engineering, aggregates smaller than 75 mm and coarser than 4.75 are called sand. Sands are divided into two categories according to the source and type of grains used in construction.
