Hospitals
MD Anderson Alkek
In the 1970s, M D Anderson built the Alkek Unit with the intention of expanding the structure as needs arose. In 2007, it was determined that the need was present, so the engineering and architectural design work began. Early in the design, Delta Structural Technology was contacted to assist with the structural upgrade to take advantage of carbon fiber technology in strenthening the internal elevator shaft walls to accommodate additional wind loads that the taller structure would encounter and a change in wind load codes. An additional problem was that the hospital must remain open and treat patients. With much cooperative engineering, Delta was able to assist the engineer of record in moving all the reinforcement inside the elevator shafts except on floors where the external walls were exposed. Also, link beams separating the elevator shafts were strengthened. The work included carbon bars embedded in the concrete and strips of carbon fiber mounted on the walls. The materials are hospital grade and odorless.

Bridges
lvie Bridge
During the drought several years ago in West Texas, the water level in Lake Ivey dropped so low that the Texas Department of Transportation was able to perform an inspection of the formerly submerged bridge columns. Upon the examination, they found severe ASR (alkali silicon reactivity) damage, characterized by massive amounts of spider cracking in the columns. For the repair, carbon fiber was applied over the cracks that had been filled and Silane applied to the concrete surface. This entire project was completed without restricting access to the bridge.

Industrial
Cambells Soup Plant
Situation:The concrete in this million square foot facility has been subjected to steam and water throughout the years. This caustic environment has lent itself to the corrosion and spalling of concrete; denigration of rebar all through the facility. In addition to this and complicating the project, several areas are running hot operations and are unable to shutdown due to yearly demand of their product line. The facility is subject to Food and Drug Administration guidelines and requires a solution that meets these criteria both during the construction process and in the completed product. Every repair through the facility required special attention to the product chosen and the methodology in its application.
Solution:Delta Structural Technology, Inc. engineered and constructed a methodology to meet the stringent demands of both the manufacturing facility and the Food and Drug Administration. Using special temperature epoxies and a mixture of carbon fiber and glass fiber reinforcement, Delta custom tailored a solution to meet each need required by the building. The final product was painted with an FDA approved paint to ensure the integrity of the composite materials and giving the plant a finished look. Delta also required no shutdown time, accommodating the facilities high demand for product, while still maintaining food safety inside the plant. In the end the building was stamped FDA approved and the customer continued operations as usual, losing no productivity time in the process.

Airport
Lago Vista
Concrete tank was repaired by crack injection and composite fiber retrofit using Tyfo™ SEH51 E-Glass. The retrofit provided corrosion resistance and structural strengthening for corrosion repair and waterproofing of the cracks from movement.

Mar 30, 2013HISTORY
Composite technology advanced rapidly in late 1960's as the Defense Department had specific interests in carbon fiber for use in defense applications, such as
the F-117 Stealth Fighter. Several leading defense contractors
began producing high strength composites to meet the strong demand from the military and
commercial aerospace industry.
