<p>The invention relates to a light-weight load-bearing structure (1) with optimized compression zone (2), where along one or more compression zones (2) in the structure (1) to be cast a core (3) of strong concrete is provided, which core (3) is surrounded by concrete of less strength (4) compared to the core (3) of strong concrete. The invention also relates to a method of casting of light-weight load-bearing structures (1) with optimized compression zone (2) where one or more channels, grooves, ducts, pipes and/or hoses (5) formed in the load-bearing structure (1) serves as moulds for moulding one or more cores (3) of strong concrete in the light-weight load-bearing structure (1). The invention further relates to a method where along one or more compression zones (2) in the structure (1) to be cast, a mould is provided for moulding a core (3) of strong concrete, which core (3) afterwards is surrounded by concrete of less strength (4) compared to the core (3) of strong concrete.</p> |
