Product description:

The declared product is a generic 1m² of precast concrete blocks. Concrete blocks are made of cement, aggregates, water and (if needed) admixtures.

The blocks covered by this EPD have been manufactured by batch moulding, where the dry components are thoroughly mixed before a measured amount of water is added and mixing continues. This semi-dry mix is fed into a mould and mechanically pressed to form the block shape. Once demoulded, the blocks are cured, in a warm and humid chamber, covered storage area or out in the open. Mortar is not included in this EPD. Primary data for the production of precast concrete blocks were collected from members of the Concrete Block Association (CBA). This data were used to generate a mass weighted average of production for the EPD.
