The basis for the geopolymers production was drawn up by prof. Kühl, well known to present day from the introduction of the modulus of clinker lime saturation. This Kühl’s formula was lined on the assumption that the best clinker should be composed of C₃S, C₃A and C₂F and the mass ratio of CaO in respect to other components is equal adequately: 2.8, 1.65 and 0.70. The analyses of the equilibrium condition in the four components system led Kühl to the so-called lime criterion, equal to the permissible maximal lime content in clinker, in the conditions far from the equilibrium. However, very little is known about Kühl’s hypothesis, which establishes that the good activators for blast furnace slag are sulphates and the slag activation was applied with lime and anhydrite, for which he obtained German patent: DRP 237777, in the year 1907. This sulphate-slag cement contained 80 – 85% of granulated slag, 10 – 15% of anhydrite and 5% of clinker. It was standardized in France, Great Britain and Germany. Also, Kühl already in the year 1907, establish the possibility of cement production from slag, activated with sodium hydroxide. Thus Kühl was the precursor of the geopolymers production. There are many studies of slag activated with the compounds of sodium and potassium. Usually, these compounds are both applicate and from some time the content of potassium silicate became higher. Gluhovsky obtained in 1958 the patent for cement obtained from slag activated with sodium hydroxide. However, the only industrial application of this binder and concrete obtained from, was the construction in 1965 of some houses in Kyiv by Gluhovsky. Gluhovsky introduced also the term “geopolymer”, which caused the storm of the critic in the former Soviet Union. In these years was in Russia many outstanding experts of the cement chemistry –alumni of Budnikov, for example, Butt and Timachev, and besides also Mchedlov-Petrosian, the organizer of 6th Congress of Cement Chemistry in Moscow, in 1974. Industrial application of geopolymers in Poland is limited to the activity of professor Małolepszy, which used this binder of blast furnace slag activated with NaOH addition to the construction of the students’ hotel, in Cracow. It should be also added that there are very few articles about the application of geopolymers for concrete production and, what is the most important, is the shortage of the papers of these binders and concretes, in the construction applications. However, there are many papers about the laboratory studies of geopolymers, activated principally by two compounds NaOH and K2SiO3. Particularly the potassium silicate is in the last time the principal activator because it accelerates the C-S-H phase formation and simultaneously increases the strength of geopolymer.
