Focus Area 2B – Production of circular cements from UK mineral resources

This focus area aims to demonstrate that it is possible to produce sustainable, circular cements suitable for many infrastructure applications by utilising UK mineral resources.

2b

Description

This project, led by Amr Aboulela and John Provis, aims to demonstrate that it is possible to produce sustainable, circular cements suitable for many infrastructure applications by utilising UK mineral resources. The technical progress in this project has been focused on defining criteria for the assessment of streams that are currently considered wastes, which are potentially feasible in terms of scale and composition to become precursors for circular cement production. This is to be implemented via a software tool that is under ongoing development, assessing materials against specified material, sustainability, and economic criteria. This tool will also build in important aspects of cement clinkerisation thermochemistry related to conventional and alternative cementitious phases and will lead to the development of an initial case study based on a clay-rich filter cake resulting from the waste treatment operations of a Sheffield-based company.

This research will bring impact through enabling connectivity between UK waste generators and potential manufacturers of circular cementitious products, who will be able to identify synergies and opportunities for new connections leading to low-carbon waste-derived construction materials.
