Cement factory is usually located near the source of raw materials. This is because cement is made from raw materials such as limestone, shale, and clay, which are found in abundance in certain geological formations. Transporting these raw materials to distant locations can be expensive and increase the cost of production, hence it is more cost-effective to locate the cement factory near the source of these materials. Additionally, proximity to the raw materials ensures a steady supply for the production process, which can be critical to the success of the factory.
