By testing the obtained samples for leaching, it was determined that the leaching rates of Si and Al are at the level of <0.5 10-3 g/cm2d, which fully satisfies the requirements for solidified liquid RAW. Geopolymer samples were tested for radiation resistance. It was found that all samples with a mineral oil content of up to 40% retained mechanical strength after gamma irradiation and the compressive strength was (16-31) MPa, which significantly exceeded the standard value (at least 5 MPa).  Product Description popup.authors Pylypenko Olexandr Svitlychnyi Yevhenii Shkuropatenko Volodymyr popup.nrat_date 2023-12-07 Close
