Cross Head Slab-Double Type
Use advice for data set A1-A3 Product stage The product stages include the raw material supply, raw material transport and product manufacturing. A1- Raw material supply The raw materials and packaging materials used to produce the Cross Head Slab were collected and calculated based on the annual production volume in 2023. A2- Transport The transport of raw materials and packaging is carried out by suppliers to the Cross Head Slab production site by various transport modes. A3- Manufacturing of Cross Head Slab All energy, industrial water, gas and environmental emission data are collected and calculated based on 2023 production year. A4- Transport of Cross Head Slab Transportation takes place between each of the life cycle stages. A4-Transport of Cross Head Slab includes transport from the Cross Head Slab production gate to the construction site. B1-B7 Use stage Module B1-B7 has been excluded according to the Product category rules NPCR 013 Part B for Steel and Aluminium Construction Products and NPCR PART A: Construction products and services. C1- De-installation / demolition This section provides information on the inputs and outputs of de-installation / demolition. Energy consumption of a de-installation / demolition process is on average 10kWh/m2 (Bozdag, Ö & Seçer, M. 2007). The average mass of a reinforced concrete building is about 1000 kg/m2. Therefore, energy consumption during de-installation / demolition is 0.01 kWh/kg. A conservative assumption has been made that the energy consumed during de-installation / demolition of a Cross Head Slab product is the same as that of a concrete building. The source of energy is diesel fuel used by work machines. It is assumed that 100% of the waste is collected and transported to the waste treatment. C2- Transport Transportation distance and truck type from the construction site to the recycling site / final disposal(landfill) is assumed as 300 km and the Lorry, 7.5-16 metric ton, Euro VI. C3- Waste processing Approximately 85% of Cross Head Slab is assumed to be recycled based on World Steel Association, 2020. C4- Disposal It is assumed that the remaining 15 % of Cross Head Slab is taken to landfill for final disposal. D Benefits and loads beyond the system boundary Steel collected and recycled is assumed to replace a value of scrap (GLO).
Technical purpose of product or process Cross Head Slab is the structure that is installed in the anchorage for fixing the strands divided from the Cross Head Slab to the anchorage. It is fixed to the concrete anchor block using a PT cable, and serves to secure the cable by strand sockets which were connected by anchor bolt, nuts and washer (m64). Produced in Korea with iron

General comment on data set Inventory data quality is judged by its precision (measured, calculated or estimated), completeness (e.g., unreported emissions), consistency (degree of uniformity of the methodology applied) and representativeness (geographical, temporal, and technological). To cover these requirements and to ensure reliable results, site site specific data in combination with consistent generic data from the Ecoinvent v3.9.1 and Industry data 2.0 was used. The LCI datasets from the Ecoinvent v3.9.1 are widely distributed and used with the SimaPro Software The allocation is made in accordance with the provisions of EN 15804. And Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. A. Allocation is avoided, if possible, by dividing the unit process into two or more sub- processes and collecting LCI data for each sub-process. B. Allocation is based on physical properties (e.g. mass, volume) when (i) there is a relevant underlying physical relationship between the products and co-products, and (ii) the difference in revenue per mass from the products and co-products is low. C. In all other cases, allocation is based on economic values of the products and co- products when they leave the unit process. 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. Also, the elements and activities excluded from the system boundaries were as follow: A. Infrastructure, maintenance efforts for infrastructure (e.g., building and machinery) B. Personnel lodging and transport, employee commute, administration

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
