In the context of construction materials, a brick is a rectangular block that is commonly used in building walls, pavements, and other structures. The earliest known bricks were made around 7000 BC in the region of modern-day Turkey and the Middle East. Bricks are extensively used in building construction for both residential and commercial purposes. Clay bricks are the most widely used type of bricks. The type of soil and its impurities have a great impact on the price of clay bricks. Brick is a clean natural material that does not affect the environment. 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. Tunisia, as one of the North African countries, offers attractive opportunities for international trade. Geographically, it holds a strategic position, serving as a gateway to markets in North Africa and the European Union. Tunisia's market is diverse, encompassing sectors such as agriculture, energy, handicrafts, and technology. In the agricultural sector, Tunisia is one of the largest producers and exporters of olives and olive oil in the world. Citrus fruits and seafood are also among the country's key export items.
