Concrete, moulded concrete part and method for the production of a moulded concrete part

摘要

The mold structure (40) has longitudinal structure (41) that is defined by a longitudinal dimension and provided with cross-section structure (30) with variable wall thickness. The ratio between length dimension (42) to minimum wall thickness (35) in the cross-sectional structure is greater than or equal to 400:7. Independent claims are included for the following: (1) concrete; and (2) method for manufacturing mold structure.
