Abstract:
Curing is crucial for the quality of the concrete edge zone and thus for the durability of concrete components. However, it has not been considered in concrete 3D printing so far. This work therefore investigates the extent to which existing curing measures can be used in concrete 3D printing. For this purpose, insights into conventional concrete construction as well as concrete 3D printing are given and the mode of action of common curing methods is explained. In concrete 3D printing, special features arise in the surface finish, the shape of the component and the formwork-free design, which have to be taken into have to be taken into account. As a result, the curing methods used up to now have been curing methods used up to now can only be applied inadequately. Therefore curing processes are adapted to the challenges and conditions of the to the challenges and conditions of concrete 3D printing. conditions. In addition, proposals for alternative processes are elaborated, with which the curing curing could be better integrated into the automated workflow. automated workflow. This work thus forms a basis for the further development and practical application of curing in concrete 3D printing.
