Engineering, low carbon concrete

About Andrew

After graduating in 2013 with an MSc in Civil and Structural Engineering, Andrew joined the Costain graduate programme and gained experience working in the Transportation team on highways and rail project delivery. In 2019, he moved to the research and development team working towards a PhD focused on low carbon concrete.

Andrew’s role and research

Concrete is the second most widely used material on the planet, releasing up to 8% of the world’s CO2 emissions. Collaborating with the University of South Wales, Andrew has developed an alternative ‘alkali activator’ from industrial waste that will reduce the carbon in concrete by up to 80%. His work is helping Costain deliver on its carbon reduction strategy and helping infrastructure clients reach netzero by 2050.

Andrew supports the Green Construction Board’s low carbon concrete group in creating a route map to inform potential clients and the wider construction sector about the benefits of low carbon concrete.

 

On how his role contributes to improving people’s lives

Andrew says the focus on a developing alternative low carbon concrete will help not only reduce CO2, but it will also help to safeguard the planet for future generations.

 

Andrew’s biggest professional achievement

Gaining an MSc in South Wales whilst working full-time on complex delivery projects in London, including the London Bridge station redevelopment, was logistically challenging and hugely rewarding.
