Experimental studies were conducted to determine the optimal composition of phosphate cement, taking into account the hardening time, strength and density indicators. The compressive strength of the phosphate matrix (40 % ash) is 23.4 MPa, which significantly exceeds the regulatory requirements (not lower than 5 MPa), and the Cs leaching rate of 1.2·10-4 g/cm2·day satisfies the requirements for the leaching rate of 137Cs (≤1· 10-3 g/cm2·day) for cement forms of waste.  Product Description popup.authors Pylypenko Olexandr Svitlychnyi Yevhenii Kholomeyev Genadii O. popup.nrat_date 2024-01-26 Close
