Thin overlays to replace the need for conventional reinforcement in additively manufactured concrete structures

增材施工技术（ACT）可以在不使用昂贵和产生废物的模板的情况下，实现具有复杂几何形状的混凝土结构的自由形式施工。然而，在ACT能够在建筑部门常规实施之前，必须克服几个挑战。其中一个主要挑战是在ACT中整合强化。在ACT中加入常规钢筋是非常困难的。为了应对这一挑战，该项目旨在开发一种易于实施的薄水泥覆盖层，以取代在增材制造混凝土结构中对传统钢筋的需求。该项目预计将促进ACT在建筑行业的采用。

Additive construction technology (ACT) can allow the free-form construction of concrete structures with complex geometries without the use of expensive and waste-generating formwork. However, several challenges must be overcome before ACT can be routinely implemented in the construction sector. One of the main challenges is the integration of reinforcement in ACT. It is very difficult to incorporate conventional steel reinforcements into ACT. To tackle this challenge, this project aims to develop an easy-to-implement thin cementitious overlay to replace the need for conventional reinforcement in additively manufactured concrete structures. This project is expected to facilitate the adoption of the ACT in the construction industry.
