Resumen:
This paper reports the results of the characterization of dolostone from a quarry of Sierras Bayas, Province of Buenos Aires,Argentina, by means of XRD and FTIR, for its application as Supplementary Cementitious Material (SCM) in blended cements. Theobjective is to study the behaviour of cement pastes and mortars with dolostone filler addition and to consider its use as alternativeto limestone. Blended cements with 0, 10, 20 and 30 % dolostone filler replacements were prepared and the heat release rate, theflowability and the setting time of the cement pastes with a w/cm ratio of 0.4 were measured. It was found that, the flowability andthe setting time, decreased as the filler content increased. Compressive strength of blended mortars (w/cm=0.50) were lower thanthat OPC mortar at all percentages and ages studied (1 to 90 days).
