Fecha de publicación: | 7-jun-2008 | Editor: | Elsevier | Citación: | Journal of Hazardous Materials [In Press] | Resumen: | This work is a continuation of a previous durability study of class C fly ash belite cement (FABC-2-W) in simulated radioactive liquid waste (SRLW) that is very rich in sulphate salts. The same experimental methodology was applied in the present case, but with a SRLW rich in sodium chloride. The study was carried out by testing the flexural strength of mortars immersed in simulated radioactive liquid waste that was rich in chloride (0.5 M), and demineralised water as a reference, at 20 and 40°C over a period of 180 days. The reaction mechanism of chloride ions with the mortar was evaluated by scanning electron microscopy (SEM), porosity and pore-size distribution, and X-ray diffraction (XRD). The results showed that the FABC mortar was stable against simulated chloride radioactive liquid waste (SCRLW) attack at the two chosen temperatures. The enhancement of mechanical properties was a result of the formation of non-expansive Friedel's salt inside the pores; accordingly, the microstructure was refined. | Descripción: | 4 pages.-- Final full-text version of the paper available at: http://dx.doi.org/10.1016/j.jhazmat.2008.05.151. | URI: | http://hdl.handle.net/10261/6314 | DOI: | 10.1016/j.jhazmat.2008.05.151 | ISSN: | 0304-3894 |
