Abstract
A concrete structure having at least one concrete insert element is disclosed. The insert element has a surface with a layer of aluminum or aluminum alloy and, upon setting of the concrete, the layer of aluminum or aluminum alloy reacts at least partially with the free lime and oxygen in the concrete to form calcium aluminate, thus providing a particularly intimate and firm bond between the insert element and the concrete.
Claims10
Concrete structure having at least one concrete insert element, which in at least a partial region is fabricated of steel and there has at least one surface embedded in concrete or cement of the concrete structure (9, 10), characterized in that the insert element (2) is provided on this surface with a layer (12) of aluminum or of an aluminum alloy, and in that this layer, upon setting of the concrete, has reacted at least partially with the free lime and oxygen to form calcium aluminate, specifically for obtaining a particularly intimate and firm bond between the concrete insert element and the concrete of the concrete structure (9, 10).
