Located in Kansas City, KS, USA, the Argentine Main Pump Station was one of three pump station upgrades that the Unified Government (Corps of Engineers) perused to increase flood protection in Argentine, Armourdale, and the West Bottoms. It was a $33 million project between all three locations. The Argentine pump station was the largest of the three. They were originally constructed between 70 to 100 years ago. The total structure (Argentine) is 57 x 59 ft (17 x 18 m).
For the project, 4500 and 5000 psi (31 and 35 MPa) ternary mixture designs were used for the walls, foundation, and mass concrete. The use of slag cement helped control the internal temperature of the concrete to keep the mass concrete placements on schedule. In addition, slag cement helped achieve early day compressive strength.
With the use of 15 to 20% slag cement, early compressive strengths were achieved. With early strength, production was sped up by 15% to complete the project.
