The production of cement / concrete, which is one of the most ecologically harmful industries, has irreparable damage to the environment. Therefore, much attention is paid to the development of technologies for obtaining alternative types of materials to cement, the so-called clinker-free binders. In particular, such materials are geopolymer binders. The purpose of this study is to develop a technology for producing geopolymer binders based on thermally modified clay rocks of Georgia, for which clay shale, mudstone and low-melting clay rocks were used. As a result of the studies, a heat treatment regime for clay rocks was developed and various compositions of geopolymer binding materials were obtained on their basis. It was found that heat treatment of the geopolymer binders significantly increases their mechanical strength. Fig. 3, Tab. 2, Ref. 30.
