Summary: | The invention relates to a concrete element comprising a core concrete layer and a face concrete layer, wherein the concrete element is obtained by compressing and curing a core concrete layer mixture in contact with a face concrete layer mixture, wherein the core concrete layer mixture contains a latent hydraulic core binder and/or a pozzolanic core binder, water, a granular core material and an alkaline core curing agent, wherein the face concrete layer mixture contains a latent hydraulic face binder and/or a pozzolanic face binder, water, a granular face material and an alkaline face curing agent, and wherein 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. |
