Research

Our Focus

SCRG’s current research and development activities are primarily focused on two main themes:

  • Sustainable Concrete Materials
  • Resilient Concrete Infrastructures

Sustainable Concrete Materials

The concrete industry is responsible for up to 7% of global carbon emissions, with most of these emissions coming from cement production, the key ingredient in concrete. Recently, there has been an increased focus on sustainability and reducing the environmental impact of concrete. Creating sustainable concrete is essential for the construction industry to lower its carbon footprint and contribute to a more sustainable future.

The “Sustainable Concrete Materials” research theme focuses on low-carbon and energy-efficient materials, including alkali-activated binders and alternative supplementary cementitious materials (SCMs). It also includes high-performance fibre-reinforced cementitious composites such as UHPC and ECC. Some of our current ongoing projects are listed as follows:

  • One-part alkali-activated binders using waste-derived activators
  • Characterisation of the strain-hardening behaviour of Engineered Geopolymer Composites (EGC)
  • Development of low-carbon Ultra-High Performance Concrete (UHPC) using alternative supplementary cementitious materials (SCMs)

Resilient Concrete Infrastructures

Repair and Rehabilitation (RnR) interventions are essential for restoring, upgrading, and extending the service life of existing concrete infrastructure. These approaches enhance climate resilience and sustainability, reduce the use of resources, and minimise carbon emissions.

The “Resilient Concrete Infrastructure” research theme focuses on both existing and new structures. By leveraging advanced materials and innovative techniques, our research develops methods to retrofit and strengthen concrete structures, thereby enhancing their performance and durability. Additionally, we focus on the analysis and design of complex concrete structures using nonlinear finite element modelling. Our current ongoing projects are listed as follows:

  • Strengthening of reinforced concrete structures using Ultra-High Performance Concrete (UHPC)
  • Carbon Fibre Reinforced Polymer (CFRP) strengthening of reinforced concrete structures
  • Analysis and design of reinforced concrete structures using Strut-and-Tie Model (STM) and nonlinear finite element modelling
  • Structural assessment of existing structures, including seismic evaluation of existing concrete building structures
