Abstract
We present a study of a synthetic Fe-substituted calcium silicate hydr ate (CSH), a constituent of cement paste, using Fe-57 Mossbauer spectr oscopy and magnetic measurements. The observed behaviour is characteri stic of antiferromagnetic nanometric particles undergoing superparamag netic fluctuations. The relevance of these findings with respect to th e understanding of CSH crystal structure and microstructure is discuss ed briefly.
