Every project has a story of how it came to be, obstacles that had to be overcome, and solutions that made the difference. These are five unique projects with concrete placement challenges, each resulting in great success.
March 1968: Crane-Mounted Conveyor Places 100 Cubic Yards per Hour
Placing concrete for an addition to a water treatment plant in North Dakota was complicated by limited access to the construction site.
September 1982: Climbing Tower Crane and Extended-Life Superplasticizer Solve Difficult Placement Problems
Two-day placement cycle achieved with three different concrete mixes.
September 1996: High-Volume Pumping Places Large Slabs Monolithically
Despite tough site constraints, project team achieves placement rates of up to 300 cubic yards per hour for the floor and roof slabs of a concrete clearwell.
September 1996: Side-Discharge Conveyor Places More Than 20 Truckloads of Concrete an Hour
When Wai Ling Engineering Co., Kowloon, Hong Kong, was awarded the contract to place concrete for the people-mover tunnels at Hong Kong's new international airport, a tight construction schedule and difficult site access required the use of special material-handling equipment.
October 2001: U.S. Seebees' Concrete Placement at 115 F
When you are in the military, you don't ask questions. But, when you are working with concrete in hot weather, you had better know the answers.
