Research summary

• Project timescale: 2019 - 2023

Using innovative concrete 3D printing processes, this project explores the potential for turning local construction and demolition wastes into recycled fine aggregate (RFA), which can then be used in concrete mortar mixes as a substitute for virgin sharp sand.

By doing so, the project addresses the carbon intensive and ecologically damaging processes of dredging and transporting virgin sharp sand, whilst creating new markets for construction and demolition wastes. 

The newly developed RFA concrete mixes will be 3D printed into various examples of urban, memorial and garden furniture established at various locations throughout North West Europe. 

The project is a €6.98million project funded by the Interreg North West Europe as part of the European Regional Development Fund (ERDF) and brings together partners from France, the United Kingdom, Belgium, Germany and the Netherlands.

Research outputs

• 25 tonnes of construction and demolition wastes recycled into RFA over the course of the project

• Up to 25 megatonnes of construction and demolition wastes recycled into RFA in the long term

• Business uptake of RFA and concrete 3D printing

• Training and networking opportunities for businesses

• A competition for students to design the furniture created as part of the project
