Cemex is planning the expansion of its Caracolito plant, which is responsible for 30 per cent of Colombia?s cement supply. The project includes the expansion of the existing quarry with an additional 110,000 sq m of land, a complete reconstruction of the kilns and the replacement of the air treatment filters. Cemex will also open a new plant in the northeast of Antioquia. Cemex?s Colombian sales have exceeded 1 mt/month in recent months.
