Innovative construction materials - the art of the possible
This is a free seminar to discuss issues that construction practitioners have when choosing sustainable and resilient materials for their projects. It will also explore how innovative materials could be applied in construction projects in light of the findings of the Materials for Life (M4L) project.

The resilience of building and civil engineering structures is typically associated with the design of individual elements such that they have sufficient capacity or potential to react in an appropriate manner to adverse events. Traditionally this has been achieved by using 'robust' design procedures that focus on defining safety factors for individual adverse events and providing redundancy. As such, construction materials are designed to meet a prescribed specification, material degradation is viewed as inevitable and mitigation necessitates expensive maintenance regimes.
The Materials for Life (M4L) project team have developed a multi-scale self-healing system in concrete using a range of interdisciplinary technologies. This will include both autogenous and autonomic self-healing materials and adaptable, self-sensing and self-repairing structures. The EPSRC funded project is a collaboration between Cardiff University, University of Cambridge and University of Bath. The project has investigated individual and combined healing techniques in the laboratory and at the field-scale. The individual healing techniques address damage at various length and time scales. These include encapsulating healing agents, bacterial healing, crack closure using shape memory polymer tendons and repeated supply of healing agents through vascular networks. Amalgamating these techniques to form a multi-scale healing system has shown to improve the overall healing efficiency with respect to strength recovery. Costain, the project’s industrial partners, have built a full-scale concrete structure in South Wales, which includes 5 wall panels incorporating different combinations of self-healing techniques. This project has been an important step in evaluating the feasibility of self-healing concrete.
In order to allow practitioners to make informed choices and take advantage of more innovative construction materials, there is a need for all stakeholders to understand the benefits and limitations of using these new approaches. Future research needs to take account of the current barriers to the adoption of innovative materials and invite people across the industry to take part in shaping the research agenda in this field.
This seminar will :
discuss issues in regards to how appropriate materials are chosen for construction projects
- highlight problems with using new and innovative materials e.g. Self-healing materials
present the results from the M4L project and how these might influence the application of self-healing materials
explore ways in which construction materials could be more resilience to climate change
provide opportunities to network with regulators, clients and other professional advisors.
