Hoosier Energy operates a coal-powered electrical generating plant at Merom Station, Indiana. The company needed a new containment pad that would serve as a holding area for processed fly ash. imi provided the concrete for this large-scale project.
At capacity, the Merom Station plant produces 150 tons of fly ash per hour. Hoosier Energy needed the concrete for the pad to contain all of the processed fly ash, be strong enough for heavy equipment to roll over, and to keep stormwater from penetrating the slab and leaching into the ground.
imi produced a 5,000 psi concrete mix that used a high-range water reducer to meet the specifications of the project. This allowed for a lower water-to-cement ratio, one of the keys to decreasing permeability in concrete, and produced a smoother finish with tighter pores.
The project also included a three-sided wall that was the base for a large windscreen. This was put in place to eliminate any fugitive dust at the site. imi delivered 2,500 yard of concrete for the footings, walls, and pad.
This project was awarded an Outstanding Concrete Achievement Award from the Indiana Ready Mix Concrete Association for Infrastructure – Energy Construction.
