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

增材施工技术（ACT）可以允许具有复杂几何形状的混凝土结构的自由形式施工，而无需使用昂贵且产生废物的模板。然而，在建筑部门例行实施共同援助社区之前，必须克服若干挑战。主要挑战之一是将强化纳入共助项目。将传统的钢筋加入到ACT中是非常困难的。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，以取代增材制造混凝土结构中对传统钢筋的需求。预计该项目将促进建筑业采用《澳大利亚首都地区法》。

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.
