Hyatt, N. C.; Jenni, Andreas; Stennett, M. C. (2010). Stability of Cs-Ionsiv in Portland cement blends for radioactive waste disposal. Materials Research Society Symposium Proceedings, 1265, pp. 221-226. Materials Research Society
Full text not available from this repository.The suitability of Portland cement blends for encapsulation of Cs-Ionsiv in a monolithic wasteform was investigated. No evidence of reaction or dissolution of the Cs-Ionsiv in the cementitious environment was found by scanning electron microscopy and X-ray diffraction. However, a small fraction (≤1.6 wt%) of the Cs inventory was released from the encapsulated Ionsiv during leaching experiments carried out on hydrated samples. Cs release was enhanced by exchange of K and Na present in the cementitious pore water. Cement systems lower in K and Na, such as slag based blends, showed lower Cs release than the fly ash based analogues. © 2010 Materials Research Society.
