Experimental studies were conducted to determine the optimal composition of the geopolymer composition based on domestic raw materials of aluminosilicate composition: fly ash, blast furnace slag and metakaolin, taking into account the hardening time, rheological properties, strength and density indicators of the manufactured samples. It is shown that hardened geopolymers containing vacuum oil up to 30 vol.% have a fairly dense and uniform structure and a compressive strength of 17 MPa after 28 days of hardening, which is quite acceptable according to regulatory requirements (at least 5 MPa). An experimental batch of samples of geopolymer composition for corrosion and radiation tests was produced.  Product Description popup.authors Svitlychnyi Yevhenii O.
