Technical purpose of product or process This LCA presents the results relating to a 1m length of 1.2m wide section of Mannok’s Hollowcore prestressed flooring 200mm thickness. The constituent raw materials of all of the products comprise sands, aggregate, cement, and prestressing steel strands. The precast products are manufactured in Derrylin Fermanagh, Northern Ireland. All concrete is batched in a 1.5m3 planetary mixer batching plant. Concrete is then placed on 1.2m wide heated formwork beds to make the hollowcore sections, and then prestressed as the concrete is poured and cured. The heated beds are heated by steam generated by LPG-fired boilers. After sufficient heating and curing the floor sections are cut into pre- determined lengths according to market requirements. Diesel-powered cutters are used to cut the hollowcore floor sections. Off-cuts of the hollowcore slabs are also produced, for trimming and cutting to order sizes. These are crushed on site, and the steel strands are separated from the crushed concrete. The steel is sent off-site for recycling. The crushed concrete is used off-site in roadbase construction. The materials and energy associated with the off-cuts are fully allocated to the hollowcore slabs sold to the market. Compositions per declared unit of the Hollowcore Slabs have been adjusted (uplifted by 1.7%) to include for the materials that are in the off-cuts. The floor slabs are manufactured to EN 1168:2005+A3:2011 Precast concrete products, hollow-core slabs.
General comment on data set Data flows have been modeled as realistically as possible. Data quality assessment is based on the principle that the primary data used for processes occurring at the production site is selected in the first instance. Where this is not available, other reference data is selected from appropriate sources. The dataset is representative for the production processes used in 2018. The process descriptions and quantities in this study are reproducible in accordance to the reference standards that have been used. The references of all sources, both primary and public sources and literature, have been documented in the LCA report. In addition, to facilitate the reproducibility of this LCA, a full set of data records has been generated which can be accessed via the EcoChain tool. This data portfolio contains a summary of all the data used in this LCA, and correspondingly, in the Mannok Hollowcore EcoChain account.

Technology description including background system A1. Raw materials supply This module considers the extraction and processing of all raw materials and energy which occur upstream to the Mannok Hollowcore manufacturing process, as well as waste processing up to the end-of waste state. A2. Transport of raw materials to manufacturer This includes the transport distance of the raw materials to the manufacturing facility via road, boat and/or train. A3. Manufacturing This module covers the manufacturing of Mannok Hollowore and includes all processes linked to production such as mixing, placing and internal transport. Use of electricity, fuels and auxiliary materials in production is taken into account as well.
