In conventional reinforced concrete, the high tensile strength of steel is combined with concrete’s great compressive strength to form a structural material that is strong in both compression and tension. The principle behind prestressed concrete is that compressive stresses induced by high-strength steel tendons in a concrete member before loads are applied will balance the tensile stresses imposed in the member during service.
Prestressing removes a number of design limitations conventional concrete places on span and load and permits the building of roofs, floors, bridges, and walls with longer unsupported spans. This allows architects and engineers to design and build lighter and shallower concrete structures without sacrificing strength.
Prestressed Hollowcore Benefits:
- Speed of construction can reduce overall project time, cost and overhead.
- Provide economical and efficient floor and roof systems
- Fire resistance can reduce insurance cost and potential loss of life and property.
- Sound control creates a better environment for occupants.
- Costly repairs or replacement due to water damage or other types of accidents are drastically reduced
compared with wood construction.
- Inside production facility, so weather delays do not affect schedule as does other methods.
- Ultra Span Hollow Core Panels by Sequatchie Concrete Service, Inc. have an excellent sound transmission class of about 50 without topping.
Prestressed Hollowcore Commercial Applications:
- High-rise office buildings
- Hospitals/nursing homes
- Parking facilities
- Prisons & justice facilities
- Retail outlets
- Athletic complexes
- Bridge deck units
Prestressed Hollowcore Residential Applications:
- Single or multiple family homes
- Garages with basement, storage, or living space underneath
- Noise wall panels
- Housing complexes/condominiums
