Limestone is primarily used as a building material and in the production of cement. It is a sedimentary rock formed mainly from the accumulation of marine organisms' calcareous remains. Its composition allows for durability and versatility in various construction projects. Additionally, limestone is used in agriculture to neutralize acidic soils and in the manufacturing of glass and lime. Its local availability and cost-effectiveness also make it an essential resource in numerous industries, including iron and steel production, where it acts as a flux to remove impurities.
