Sustainable Construction Materials

Ravindra Kumar Dhir OBE is an honorary professor of concrete engineering, University of Birmingham, United Kingdom; adjunct professor at Trinity College Dublin, Ireland, and emeritus professor of concrete technology, University of Dundee, United Kingdom, where he held the position of founding director of the Concrete Technology Unit (1988-2008) and developed it into an internationally acknowledged Centre of Excellence. His approach to research is visionary and creative, and by working closely with industry, he ensured a meaningful dissemination of his research into practice. He won many awards and honours,including the Order of the British Empire for services to concrete technology from the Queen (1998), Secretary of State for Trade and Industry for innovative partnership withindustry (1989 and 1990 consecutively) and honorary fellowships from the Institute of Concrete Technology, United Kingdom; Indian Concrete Institute. He served on numerous technical committees, including as president of the Concrete Society (2009-2010) and on the editorial board of the Magazine of Concrete Research. Dr Gurmel S. Ghataora, Senior lecturer, University of Birmingham, UK. Over 40 years’ experience in the geotechnical engineering industry and academia. He has been at the University for over 25 years, where in addition to his teaching, he is the Head of Postgraduate Admissions for all taught programmes in Civil Engineering. He has supervised over 50 research students and authored over 180 articles. His interests include geotechnics of earth roads and railways, and sustainable construction materials. Amongst his many inventions are zero-compaction trench backfill made from as-dug materials, fibre reinforcement of clayey soils, improving the stiffness of railway tracks without removing the track, a novel railway drainage system and remediating acidity in colliery spoil using waste materials. Current studies include the durability of concrete made with recycled concrete aggregate and municipal incinerated bottom ash. He is a member of the Institute of the IOM3 and sits on two TRB committees. Ciaran J. Lynn, PhD doctoral researcher, University of Birmingham, UK. He received his MSc in Engineering from Trinity College Dublin, Ireland and BE in Civil Engineering from University College Dublin, Ireland. His research interests lie in the areas of sustainable construction and the appropriate use of secondary and recycled materials, including in concrete, geotechnics, road pavements and ceramic applications. He is an active contributor in these areas, including publications on the use and environmental assessment of incinerated ashes as construction materials. He is currently involved in a number of ongoing projects focusing on sustainable concrete construction.
