摘要：Immobilization by cementation of anionexchange resins is closely associated with high pHvalues of a cement matrix as a result of compositional buildup of the cements used as binding agents. At high pH values the anionexchange resins with acid reaction (pH<5) start recycling in a body of the hardening cement compound resulting in its destruction. The paper covers the results on efficiency of the hybrid alkali activated cements as binding agents which at the initial stage of hydration have high pH values of the cement stone (pH>12), thus providing a required strength gain. Later, pH values tend to lower (pH<10), thus retarding the process of resin recycling to the values which do not affect negatively durability of the resulted solidified waste forms. The examples of hybrid alkali activated cements compositional build up are provided together with physicomechanical properties of the resulted solidified waste forms. These results show that these properties are superior to those specified in the standards of the P. R. China, these are: GB 7023 and GB 14569.
