John Kinuthia

Professor John Kinuthia is a leading academic in sustainable construction materials at the University of South Wales, heading the Advanced Materials Testing Centre. His research focuses on developing eco-friendly building materials using industrial/agricultural waste, with expertise in geopolymer concrete, soil stabilization, and nanomaterials. He holds a PhD in Civil Engineering Materials from the University of Glamorgan (1997), an MSc in Highway Engineering from the University of Birmingham (1988), and a BSc in Civil Engineering from the University of Nairobi (1983).

Research Interests: Professor Kinuthia’s work emphasizes sustainable construction through innovation in materials like unfired clay bricks, recycled plastic aggregates, and geopolymer systems. His research integrates environmental sustainability with practical applications, including cost-effective housing solutions for Africa supported by UNESCO. Notable expertise includes:

• Utilization of industrial by-products (GGBS, PFA, rice husk ash)
• Soil stabilization with lime/silica blends
• 3D printing in construction
• Smart concrete technologies

Recent Article Trends: Over 80 publications (2025-1995) emphasize geopolymer systems, recycled materials, and sustainable binders. Key areas include:

• Low-carbon construction materials
• Waste plastic aggregate utilization
• Alternative activators for geopolymers
• Climate-resilient road construction

Scientific Awards: Royal Society Brian Mercer Award for Innovation (unfired systems). External roles include External Examiner at University of Ulster (2014-2018) and University of Zambia (2010-2012).

Advisory Work: Supervised 11 academic works and actively collaborates with industries. His Advanced Materials Testing Centre facilitates applied research in construction materials innovation.

Labs/Initiatives: Leads the Engineering Research and Innovation Group, focusing on advancing materials science through interdisciplinary approaches. Current projects explore carbon-neutral construction solutions and smart material systems.
