Purpose and goal
The purpose of the project is to introduce functionalized graphene into cement based coating material to improve its mechanical properties. The volume product of functionalized graphene can be obtained for painting up to 100 m2 areas of walls. Compared with cement paint itself, the addition of graphene improves the bending performance, provides better adhesion with cement based substrates and is more resistance to chloride penetration.
Expected results and effects
The enhancement of graphene in the cement paint was observed within this project. The improvement level is in the range of 20-50%. The influence of functionalized graphene on cement paint from different batches also need to be evaluated to prove the repeat-ability of production process. A following project is planned focusing on some mechanical properties, up scaling of functional graphene production and full size demonstration project in exposed environmental sites with long term evaluation.
Planned approach and implementation
The project provides the chance to work with graphene-enhanced cement paint in certain quantity. We are happy to work with all the partners in the present consortium. For next step, we need more understanding on hydration process and binding formation on the cement paint with graphene. SHT will improve the repeat-ability of up-scaling process of functionalized graphene and Lanark will improve the base material of cement powders. It is expected that the first product of graphene enhanced cement paint could be matured within 2-3 years.
