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.

Health tourism and the provision of technical and engineering services are also among the areas that have grown significantly in recent years. In the field of health tourism, a large number of Iraqis travel to various cities in Iran each year for treatment. Religious tourism is another type of tourism that has grown significantly between Iran and Iraq in recent years.

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.

Iraq also has houses in the city center with an average price of $1,896 per square meter and an average price of $875 per square meter outside the city. The wealthy and well-connected dominate the Iraqi housing market. Many of these wealthy individuals are tired of taking their money out of Iraq due to Western sanctions and are therefore turning to local investments within Iraq.
