Abstract


In this work, which is the following of the others, the performance of a portland cement of a high initial resistance (P-550-ARI) —with a calculated content (Bogue) of 39,2 - 25,7 - 9,9 - 12,0 and 6,9% of C3S - C2S - C3A - C4AF and CaSO4, respectively— is studied when it is submitted to the action of an sodium sulfate solution [2,1 g/l of Na2S04 < > 1,42 g/l of SO4 (II) < > 1,48 X 10-2 moles/litre of SO4 (II)] running across the beds of granulated cement, made with this hydrated cement cured during 7 or 28 days, determining: a) The evolution of the content on ions Ca (II) and SO4 (II) on the taken diverse fractions of sodium sulfate solution which have run across those beds, so as this of the pH and of the conductivity, b) the variation in the amount of these ions that are forming the correspondents compounds, in the hydrated cement from the beds that have been submitted before and after to the action of the sodium sulfate solution, and c) the structural modifications undergone by the crystalline compounds of the hydrated cement from the beds submitted to the action of the sodium sulfate solution.
