Gypsum plaster, also known as plaster of Paris, is a type of plaster made from the mineral gypsum. The use of gypsum and plaster dates back thousands of years, with evidence of its use in ancient civilizations. Plaster is extensively used in the construction industry for interior finishing and decorative purposes. One of the primary uses of plaster and gypsum in construction is for interior wall and ceiling finishing. Gypsum is widely used in agriculture as a soil amendment and nutrient source. 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. Colombia's economy is classified as a middle-income, emerging market economy that has seen steady growth over the past decades.
