Sand is a granular material composed of finely divided rock and mineral particles. The construction industry is the largest consumer of sand globally. Sand plays a crucial role in various construction materials due to its physical properties and ability to enhance the performance of building components. Sand is typically extracted from natural sources through different methods, depending on the location and type of deposit. River sand is naturally occurring sand found in riverbeds or banks. 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. Its key sectors include oil, mining (notably coal and gold), agriculture (with coffee, bananas, and flowers being major exports), manufacturing, and services. Colombia has adopted open-market policies, implementing free trade agreements (FTAs) with numerous countries and regions, including the U. S. , the EU, and countries in Latin America. Colombia's fiscal policy is geared towards encouraging foreign direct investment (FDI), promoting exports, and diversifying its economy beyond dependence on natural resources.
