| Technical purpose of product or process | ollow core is a type of slab that is made of concrete and contains prestressed reinforcement. The elements have longitudinal air channels to optimize material use and load-bearing capacity. The hollow cores are manufactured in different thicknesses depending on the desired function. This type of slabs allows for large spans, which also provides good conditions for a flexible use of the building over its lifetime. It is also a very resource-efficient product that utilizes the included material optimally. The low w/c ratio and the high strength mean that the construction dries out quickly. With hollow core slabs, the building also receives very good properties in terms of sound insulation and good resistance against fire and moisture. Another of the concrete's important properties is its ability to store heat, which enables a low energy consumption and a lower power output during the building's entire operating time. Hollow cores are 100% recyclable and enable fast, cost-effective and rational assembly in the construction project. This type of slab is also well suited for reuse. |

| 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 | Declared element is HD/F 120/27 in concrete quality C45/55, w/c ratio 0.40 and with 6 tension lines Ø12.9. However, this EPD is applicable for dimensions HD/F 120/20 - HD/F 120/50 as the environmental impact indicators do not differ by more than 10% from the declared value. Production weight for HD/F 120/27 is 367kg/m². Cement is Heidelberg Materials Bascement CEM II 42.5 R. See EPD-HCG-20210157-CAA1-EN More technical data and information on load capacity for different hollow core dimensions is available at Heidelberg Materials Precast Contiga's concrete factory in Uddevalla. |
