Fecha de publicación: | abr-2003 | Editor: | Elsevier | Citación: | Cement and Concrete Composites 25(3): 287-292(2003) | Resumen: | A mechanical, mineralogical and microstructural characterisation of the cement pastes obtained by alkaline activation of fly ash/slag mixtures cured at different temperatures has been carried out. The pastes obtained were characterised by XRD, FTIR, MAS NMR, SEM/EDX, atomic absorption and ion chromatography, also the insoluble residue in HCl was determined. The results obtained have proved the existence of two different reaction products in those activated pastes. The average atomic ratios in the main reaction product were Ca/Sinot, vert, similar0.8, Al/Canot, vert, similar0.6, Si/Alnot, vert, similar2–3. Such analysis corresponds to calcium silicate hydrate rich in Al, which includes Na in its structure. Other reaction product which was detected in the pastes as result of fly ash activation, was an alkaline aluminosilicate hydrate with a three-dimensional structure. | Versión del editor: | http://dx.doi.org/10.1016/S0958-9465(02)00059-8 | URI: | http://hdl.handle.net/10261/31990 | DOI: | 10.1016/S0958-9465(02)00059-8 | ISSN: | 0958-9465 |
