Abstract
The disclosure relates to a method for producing a dimensionally stable concrete work-piece characterised in that to produce the concrete work-piece a fully-sealed dimensionally stable form is filled with fresh concrete in a predetermined geometry, during the subsequent and undisrupted hydration a predetermined temperature distribution of the walls of the form surrounding the hydrated concrete is carried out and the concrete workpiece is shaped at a compressive strength of more than 10 MPa.
Claims14
A method for producing a dimensionally stable concrete workpiece, the method comprising:
- for the production of the concrete workpiece, a fully sealed mould, dimensionally stable in a predetermined geometry, is completely filled with fresh concrete, a predetermined temperature distribution of the walls of the mould surrounding the hydrating concrete is set during the subsequent and undisrupted hydration and the concrete workpiece is removed from the mould with a compressive strength of more than 10 MPa, wherein the maximum grain size of the fresh concrete has a diameter of less than 20% of the smallest dimension of the mould;
- and
- wherein the temperature distribution of the walls of the mould is set such that the temperature distribution in the hydrating concrete from the start of the hydration up to the formwork removal lies within a permitted range of 15° C.
