There are analyzed the possibilities of production of new geopolymeric binder materials by inclusion of small amounts of these condensed materials into industrial waste and using phosphoric acid.

Based on this, the development of technologies for new energy-efficient building materials - substitutes for Portland cement is of great importance. One of the ways to solve this problem could be the wider use of ceramic building materials, the production of which requires less energy and is not associated with high CO2 emissions compared to the production of Portland cement. The subject of this article is the development of innovative technologies for the production of ceramic building materials in Georgia (ordinary building bricks and clinker bricks) by using unconventional raw material - clay shale aluvium which is a waste of natural (exogenous) processes. As the main component of the ceramic mass, we used clay shale aluvium from the Duruji river bed near the town of Kvar...

Geopolymer binders are considered a promising basis for creating a technological platform for the resource-saving building materials industry. These materials have a number of valuable properties and in the near future may serve as an alternative to modern binders based on Portland cement. The main raw materials for the production of geopolymers are natural and artificial aluminosilicate materials (kaolin and ordinary clay rocks, feldspars, slags, fly ash and other), the hardening of which is activated by low-modulus alkali metal silicates. The article is devoted to the development of technology for the production of geopolymer binders based on thermally modified clay rocks of Georgia, such as shale, mudstone and low-melting clay.
