TIRONI, A; TREZZA, M; IRASSAR, E and SCIAN, A. Thermal activation of bentonites for their use as pozzolan. Revista de la Construcción [online]. 2012, vol.11, n.1, pp.44-53. ISSN 0718-915X. http://dx.doi.org/10.4067/S0718-915X2012000100005.
The reactivity of two calcined bentonites from different regions of Argentina for use as pozzolanic additions to Portland cement were analyzed. Through techniques of XRD, IR spectroscopy, tests of lime consumption and mechanical strength were relations structural changes, occurring during heat treatment, with pozzolanic behavior.
