text: With respects to archaeological applications, in the mid-1980s, Joseph Davidovits  presented his first analytical results carried out on genuine pyramid stones. He claimed that the ancient Egyptians knew how to generate a geopolymeric reaction in the making of a re-agglomerated limestone blocks. The Ukrainian scientist G.V. Glukhovsky endorsed Davidovits' research in his keynote paper to the First Intern. Conf. on Alkaline Cements and Concretes, Kiev, Ukraine, 1994. Later on, several materials scientists and physicists took over these archaeological studies and are publishing their results, essentially on pyramid stones.
