Transcript of the conference by Prof. Joseph Davidovits, held at the Geopolymer Camp 2018, in the Session: In the 1950s, Viktor Glukovsky, of Kiev, USSR, developed concrete materials originally known under the names "soil silicate concretes" and "soil cements", but since the introduction of the geopolymer concept by Joseph Davidovits, 1991, the terminology and definitions of 'geopolymer' have become more diverse and often conflicting. His current research projects include developing carbon-friendly cement-free geopolymer materials, and development of sensors for monitoring scour at bridge foundations. Ordinary Portland Cement (OPC), which is the main ingredient for concrete production, contributes about 10% of the global carbon dioxide (CO2) emission. Geopolymer cement is a binding system that hardens at room temperature. 1, the side length of the plate is 1 mm, and a horizontal crack with a length of 0.5 mm is prefabricated on the left edge.First, a vertical upward tensile force is loaded to the top of the plate to simulate mode I crack propagation.
