Peavey–Haglin Experimental Concrete Grain Elevator

The Peavey Haglin Experimental Concrete Grain Elevator is a 1899-1900 erected round silo of concrete for the storage of grain and was the first building of its kind in the United States and possibly the world. He is notable because he has proven the possibility of using concrete in the construction of grain silos. Previously, these were built of wood and were therefore more costly and fire- prone. He stands in St. Louis Park near the intersection of Minnesota State Route 7 and Minnesota State Route 100 on a former railway line of the Minneapolis and St. Louis Railway.

The building was given by Frank Peavey, which owns a major grain trading company in order and planned by the engineer Charles F. Haglin from Minneapolis and built. This also built as a building contractor, the Minneapolis City Hall, the Grain Exchange Building, the Pillsbury Building and the Radisson Hotel. The silo was built by allowing concrete to flow into wooden forms that were held together by steel tires. The engineers were hesitant at first because they did not realize how much pressure can tolerate the building and therefore limited the height to 68 feet, about 20.7 m. After a stress test in which the silo was filled and emptied, elevated to the building up to its present height of 125 feet ( about 38 m). The internal diameter is 20 feet (6.1 m) and the wall thickness is 12 inches ( 30.5 cm) in the vicinity of the foundation and takes up to the top 8 inches ( 20.3 cm) from.

Although the load test was successful, the silo was never refilled, but its manner of construction paved the way for many other grain silos in this type across the United States.

Because the building is remarkable, it was registered on 19 December 1978 in the National Register of Historic Places, declared on December 21, 1981 National Historic Landmark and was added in 1983 by the American Society of Civil Engineers in the List of Historic Civil Engineering Landmarks.
