摘要：
The durability of mortars fabricated with two kinds of low-energy cements containing hydrothermally activated Spanish fly ashes is presented. The study has been carried out by means of the Koch-Steinegger test at 21+/-2 degreesC for 180 days. The durability was evaluated from the changes of flexural strength of the mortars after immersion in the potential aggressive solution (0.5 M NaCl+0.5 M Na2SO4) compared with those obtained in similar samples immersed in demineralized water. The changes in microstructure were followed by mercury intrusion porosimetry (MIP) and mineralogy by X-ray diffraction (XRD). (C) 2000 Elsevier Science Ltd. All rights reserved.
