He is currently a member of the advisory committee to the Algerian ministry of higher education and research (Comité sectorial permanent CSP) (2016-) as well as the CSP of the ministry of Housing (2022-). He is a consultant in charge of quality control and inspection and diagnosis of buildings at the “Société de consultancy and Testing Engineering (SCTE)”, Algiers.

He has co-authored over 150 international journal and conference papers and three ELSEVIER and SPRINGER chapters on recycled aggregates and NDT. He is a member of the editorial board of many journals such as ‘Materials and structures’ of the RILEM, SPRINGER, “advances in concrete construction” of the techno-press, the open civil engineering journal, Scientific Advances Journal of civil and construction engineering, India, Beirut Arab University Journal (Lebanon). He is a reviewer of several international journals. He has been invited as a keynote lecturer in many conferences in Brazil, South-Africa, Jordan and Egypt. He has collaborated on many research projects with colleagues in Belgium, France, England, USA, Brazil and South-Africa. He has been on the Stanford 2022 list of top 2% scientists in the world in the field of building engineering with an H-index of 30.

His main research interests include concrete durability, recycling, earth constructions, self-compacting concrete, non-destructive testing and repair and strengthening of structures.


Joseph J. Assaad is Professor of Civil Engineering at the University of Balamand. He earned his Ph.D in 2004 from Sherbrooke University, Quebec, Canada. His research interests include a variety of topics related to Civil and Structural Engineering such as modern cement clinkers, alkali-activated geopolymers, thixotropy, rheology, formwork pressure, bond to steel reinforcement, microstructure, durability, 3D printing, polymer-modified cementitious materials, recycling of aggregates and other waste materials, and sustainability in construction. Dr Assaad authored over 120 referred international papers, reviewed over 600 research papers, and published 2 books in 2009 and 2017 about thixotropy and applicability of geotechnical principles to cementitious materials. His current h-index is 33 (according to Scopus) with more than 2800 citations, which ranked him among the top 2% worldwide researchers according to the Stanford Study. Dr. Assaad received numerous local and international distinctions and awards in the field of cement and concrete technology including the Research Excellence Awards awarded by CNRS-Lebanon (2014) and Société de la Légion d’Honneur Franco-Libanais (2016) for his outstanding contribution to research and exposure of the Lebanese scientists to the international community.

Prof. John Kinuthia


Professor, University of South Wales, UK


Professor John Kinuthia is the head of the Advanced Materials Testing Centre. His research is into the development of sustainable building and construction materials by utilising natural, industrial and agricultural waste and by-product materials. He has special expertise in soil and cement-based cementitious systems, incorporating emergent concepts technologies such 3D printing, smart concrete, as well as nano- and geo-polymer materials. Engagement with industry and enthusing teaching enhances satisfaction in these research interests. Professor Kinuthia was awarded the Royal Society Brian Mercer Award for Innovation on unfired scaly systems. The deployment of these novel materials into Africa, to provide new homes at lower cost, was supported by UNESCO.
