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

外加建筑技术(ACT)可以自由建造复杂几何形状的混凝土结构，而不需要使用昂贵的和产生废物的模板。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。主要挑战之一是在ACT中整合配筋。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型水泥基覆盖层，以取代在额外制造的混凝土结构中使用传统钢筋的需要。该项目预计将促进ACT在建筑业的采用。

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.
