Abstract (en)

[origin: CA3224132A1] The invention relates to a concrete element comprising a concrete core layer and a concrete facing layer, wherein: the concrete element is obtained by compressing and curing a concrete core layer mixture in contact with a concrete facing layer mixture; the concrete core layer mixture contains a latent hydraulic core binder and/or a pozzolanic core binder, water, a granular core material and an alkali core curing agent; the concrete facing layer mixture contains a latent hydraulic facing binder and/or a pozzolanic facing binder, water, a granular facing material and an alkali facing curing agent; and the concrete element has a compressive strength in accordance with DIN EN 12390-3, in particular DIN EN 12390-3:2019-10, measured after 28 days, of less than 120 N/mm2. The invention also relates to a method for producing the concrete element and to the use of a latent hydraulic binder and/or pozzolanic binder together with an alkali curing agent to produce the concrete core layer in the concrete element.
