| Technical purpose of product or process | Solid concrete walls are a homogeneous element that is usually used as an interior or exterior wall. The walls are cast on horizontal mold tables with one side that is counter-moulded and with one side that is machined, up in form. Walls are manufactured in different thicknesses depending on the desired function. With concrete walls, very good properties are obtained in terms of sound insulation, fire resistance and moisture safety. Another of concrete's important properties is its ability to store heat, which enables low energy consumption and a lower power usage during the building's entire operating life. Concrete walls are 100% recyclable and enable fast, cost-effective and rational progress in the construction project. |
| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |

| Technology description including background system | The declared element is a 1-tonne concrete wall, 200 mm thick, made of concrete strength class C40/50 with a water-cement ratio (w/c) of 0.45. It contains an average reinforcement of 20.9 kg per tonne and an average amount of cast-in steel of 2.59 kg per tonne. The declared unit also applies to wall thicknesses from 150 mm to 400 mm, assuming average reinforcement and cast-in material quantities. The cement used is Heidelberg Materials Bascement Plus Slite CEM II. See NEPD-11488-11382 for reference. Concrete strength C40/50. Exposure classes up to XC4-XS2-XD2-XF1. Life length class up to L100 (100 years). More technical data and information about load capacitys for the different wall dimensions is available at Heidelberg Materials Precast Contiga's concrete factory in Norrtälje. |
