An AECOM-led joint venture constructed one of the world’s largest cement plants on 3,900 acres 45 miles south of St. Louis, Missouri.
The facility’s single kiln (300 feet long by 21 feet in diameter) produces 12,000 metric tons of clinker per day (4 million tons per year), making it the largest single clinker production line in the world.
The project scope included construction of the primary and secondary crushers, limestone dome, raw-meal-feed structure, raw mill and raw-meal silos, 360,000-square-foot additives storage building, preheat tower, kiln, clinker cooler and silos, finish mills and cement silos. Bounded by the Mississippi River on the east, the complex also incorporates a harbor that extends to the Mississippi, where most of the plant’s finished product is loaded on barges for transport.
The facility has the most advanced equipment and technology available, providing for emission limits among the lowest of any cement plant in the United Sates and the world.
