Scope: When faced with the challenge of a marine/mass concrete pour on Poplar Island on Maryland’s Eastern Shore, GFP’s mission was to make certain this logistically burdened project would run as smooth and efficiently as any mainland project.
In response to a large concrete pour on Poplar Island, GFP Mobile Mix Supply LLC was contacted because of our volumetric mixer capabilities. The concrete spillway structure to be constructed for the Army Corps of Engineers was considered to be a “mass concrete pour” because of the sheer volume of the structure. As such, additional engineering and monitoring steps had to be adhered to in accordance with USACE Specifications to control the potential for cracking from thermal stresses. GFP ran several trial mix designs and ultimately a mix design of 60/40 Cement and Slag was selected, combined with water conditioning of the coarse aggregates and batching with chilled water, to meet the requirements of the thermal control plan. GFP mobilized a 20,000 gallon Mobile Chiller Plant, over 400 tons of Sand, Stone and Cement, Four Volumetric Concrete Trucks and One Pump Truck for a successful 140 yard pour on Poplar Island.
