Technical purpose This average product EPD is for Moore Concrete's precast concrete bunker wall. The results presented in this EPD are the results for a weighted average of the concrete mixes and steel reinforcement of the bunker wall products manufactured by Moore Concrete in 2021. The raw materials are cements, GGBS, aggregates, admixtures, reinforcing steel and lifting accessories. In addition, consumables include steel and timber for formwork, release agents and curing agents, plastic and concrete spacers. The products are manufactured in accordance with the following standards: EN 13369 'Common rules for precast concrete products'; EN 15258 'Precast concrete Products. Retaining wall elements'.
The precast units are delivered to site on flat-bed trucks. No product packaging is used in the delivery to the customer, other than re-useable wood skids, as and when needed. The precast products are manufactured from cement and cement replacements, aggregates, water and a variety of admixtures. The concrete mix ingredients are batch-weighed, mixed and dropped into a hopper that is transported across the factory hall so that the fresh concrete is then placed into the selected formwork/mould.
The moulds are prepared with a mould oil, reinforcing bars and spacers before the mix is poured. Once the fresh concrete is placed in the moulds, the surface is sprayed with a curing agent to assist curing. The moulds are left in place on the factory floor to allow the concrete to cure. Demoulding of the precast concrete elements takes place once the correct strength has been achieved. Units are finished in the factory and transported to a storage area. |
