Abstract

The building materials industry in Georgia is entirely based on the production of Portland cement and concrete
made from it, which is a particularly energy-intensive and environmentally harmful production. Considering the high prices
for fuel and in the light of unfavorable environmental conditions in the country, the development of technologies for
obtaining new alternative types of binders that do not require high-temperature firing is especially urgent. These materials
can be geopolymer binders. The purpose of this work is to identify the possibility of obtaining and studying the properties of
geopolymer binding materials of alkaline activation based on thermally modified clay rocks of Georgia, as well as
geopolymers of acid activation using local industrial waste - dump blast furnace slags.

Key words: geopolymer, alkali activation, acid activation, clay rock, dump blast furnace slag, magnetite.
