Dr Raffaele Vinai

Senior Lecturer in Civil Engineering

Location: Harrison 181

Telephone: 01392 723627

Extension: (Streatham) 3627

Raffaele graduated from the Turin Institute for Technology (Politecnico di Torino – Italy) in 2002 (MSc in Environmental and Land Engineering) and obtained a PhD in Geo-Environmental Engineering in 2006 from the same institution, spending 6 months as Academic visitor at the University of Oxford (UK). After a professional experience as project coordinator and area manager in East Africa with a Non-Governmental Organization (2006 – 2009), he returned to Academia as lecturer at the International Institute for Water and Environmental Engineering in Burkina Faso (2010 – 2011), as Head of the Education and Research Unit of Infrastructures and Material Science and Coordinator of Eco-Building Material Laboratory. After a collaboration with the Turin Institute for Technology (Politecnico di Torino – Italy) in 2012 – 2013, he worked at the Queen’s University of Belfast (2013 to 2017) as Research Fellow, being involved in several projects focussed on the development of sustainable concrete made with recycled waste materials, geopolymer concrete, alkali activated binders and recycled aggregates. He joined the University of Exeter in January 2018. He is an author or co-author of more than 70 scientific publications. His research interests include sustainable construction materials, waste recycling, geo-materials. He is chartered engineer and member of the Institute of Materials, Minerals and Mining.

Low carbon building materials

Waste and co-products management is a pressing issue, as well as the need for low cost, low carbon, safe and locally available building materials with improved thermal insulation properties.

The 2008 Climate Change Act declares a target reduction of the UK’s greenhouse gas emissions by 100% (from the 1990 baseline) by 2050. The built environment is responsible for some 40% of energy consumption and 36% of CO2 emissions. Energy consumption, and associated greenhouse gas emissions, is derived from whole life cycle, including manufacture of products, construction, maintenance and disassembly (e.g. embodied energy) as well as operational energy during building’s use. Building sector is therefore a key player in the global emission reduction.

Recent research projects:

2022

Dr Vinai obtained a grant for the project “SHUTTERING: Low carbon concrete Structures witH aUxeTic TextilE foRmworks as reinforcING element”, EPSRC Sustainable Manufacturing Call Full Proposals Invite Only, £1.8M FEC (~£926k EPSRC funds to Exeter) as PI, with Co-Is Dr Prakash Kripakaran and Prof Ken Evans, in partnership with Dr John Orr at the University of Cambridge.

Dr Vinai collaborated with Agrikinetic ltd (UK) through the Open Innovation Platform funding led by the Innovation, Impact and Business (IIB) team at the University of Exeter.

2020

Dr Vinai collaborated with ARC Marine ltd (UK) through the SBRI funding from Innovate UK. A research contract of £20k was obtained for determining technical specifications of artificial reef deployment and LCA.  

2019

Dr Vinai obtained a £48k grant from EPSRC Early Career Researcher Capital Fund 2019 for the procurement of an environmental chamber for controlling moisture, temperature, CO2 content for conditioning and testing, and a mercury intrusion porosimeter (MIP) for assessing the porosity, bulk and apparent density, particle size and pore related properties of developed materials.

Dr Vinai collaborated with ARC Marine ltd (UK) through the Open Innovation Platform funding led by the Innovation, Impact and Business (IIB) team at the University of Exeter. A funding of £15k has been allocated for the investigation of low carbon concrete for marine applications.
