Technical purpose Product Name and Specification
The declared product, Heda Hybridbjälklag is a prefabricated Timber-Concrete Composite (TCC) slab.
Intended Area of Application
The TCC slabs are designed to be used as load-bearing structural elements, primarily as intermediate floors in residential, commercial, and public buildings.
Technical and Functional Characteristics
The product combines the tensile strength and lightweight properties of sawn timber with the compressive strength and acoustic mass of concrete. The main raw materials are Portland cement, aggregates, reinforcing steel, spruce or pine timber, additives, and water. Any other raw materials account for less than 1% of the total mass.
• Concrete strength class: C40/50.
Unambiguous Identification & Test Standards
The prefabricated elements are designed, detailed, and executed in accordance with SIS-CEN/TS 19103:2022 (Design of timber-concrete composite structures). The structural design further complies with the general assumptions of the Eurocodes, intended to be used in conjunction with:
• EN 1990: Basis of structural design
• EN 1991: Actions on structures
• EN 1992: Design of concrete structures
• EN 1995: Design of timber structures
Reference Service Life (RSL)
The design service life of the structural elements is dependent on the client’s specific requirements and the building category, typically specified as either 50 or 100 years in accordance with EN 1990 for quasi-constant environmental conditions. As the use stage (Modules B1-B7) is not declared in this EPD, a formal mathematical RSL is not applied in the LCA calculations, but the physical durability of the product supports the aforementioned design lives. |
