Clay is a naturally occurring fine-grained mineral substance composed primarily of hydrated silicates of aluminum. Clays can have different mineral compositions based on the parent rock from which they were derived and the specific geological processes involved. Clay is extensively used in the production of ceramics and pottery. Clay is a highly versatile material that can be molded, shaped, and formed into various objects and structures. One of the most widely used construction materials, concrete is a mixture of cement, aggregates (such as sand and gravel), water, and additives. The Middle East has experienced a construction boom in recent years, driven by urbanization, population growth, and ambitious development plans. Construction sand, typically sourced from rivers, quarries, or coastal areas, is a fundamental component of concrete, mortar, and other construction materials. Clay is a primary ingredient in the production of bricks and blocks. Spain is one of the member states of the European Union and an important market for international trade.
