STUDY OF PHYSICAL CHARACTERISTICS OF FRESHLY PRODUCTION FLY-ASH FROM THE EXHAUST GASES OF COAL-FIRED POWER STATIONS

ETAT DES CONNAISSANCES RELATIVES A L'UTILISATION EN REMBLAIS ROUTIERS DE CENDRES VOLANTES DE FRAICHE PRODUCTION PROVENANT D'UNE OU DE PLUSIEURS CENTRALES ELECTRIQUES

The physical and geotechnical characteristics of freshly produced fly-ash collected using dry methods from the exhaust gases of, for the most part, coal-fired power stations, were studied in the laboratory and on a pre-experimental site with a view to their use as a road embankment material. When subjected to certain conditions governing state, saturation, and stress, fly-ash used in embankment can undergo liquefaction if it has been inadequately compacted (below a certain critical density). The critical density can be determined in the laboratory by means of prolonged and delicate triaxial tests, which is difficult to reconcile with the tempo of the works on this type of site.
