Muhammad N. S. Hadi

Muhammad N. S. Hadi is an Iraqi Australian civil engineer and an academic. He is a professor of engineering at the School of Civil, Mining, Environmental, and Architectural Engineering, University of Wollongong.

Hadi has conducted research on concrete structures and fiber-reinforced polymers (FRP). He has co-authored three textbooks, including Nonlinear Analysis of Concrete-Filled Steel Tubular Columns and Concrete-Filled Stainless Steel Tubular Columns.

Hadi's work has been cited 9,600 times according to Scopus.

Education and career Hadi earned his B.Sc. (Hons) in Civil Engineering and his M.Sc. in Structural Engineering from the University of Baghdad, Iraq in 1977 and 1980, respectively. Between 1975 and 1984, he worked at the Rafidain Engineering Laboratory, the Air Force during his military service, and the Al-Mustansiriya Consultancy Bureau in Baghdad. He went on to complete his Ph.D. in Structural Engineering from the University of Leeds in 1989. In other research, he calculated the optimum design of beams under different loadings using neural networks and showed that neural networks are comparatively effective for solving a vast number of structural engineering problems.

In his later work, Hadi employed the Taguchi method to find the best mix for geopolymer concrete, using ground granulated blast furnace slag (GGBFS) as a substitute for regular cement. He subsequently demonstrated that the setting time improved with the addition of metakaolin and silica fume. In related research, he investigated different factors affecting the strength, setting time, and workability of geopolymer pastes and after testing different mixes, found that the best mix consisted of 40% of GGBFS, 0.5 of Al/Bi ratio, 2.0 of SS/SH ratio, and an Aw/Bi ratio of 0.15.
