Estimation of Chloride Migration Coefficient in Air-Entrained Concretes Containing Fluidized Bed Combustion Fly Ash / Ocena Współczynnika Migracji Jonów Chlorkowych W Betonach Zawierajacych Popiół Fluidalny

[摘要] The objective of this investigation was comparing the penetration of chloride ions in ordinary and air-entrained concretes containing a waste material Fluidized Bed Combustion Fly Ash (FBCFA). All concretes were tested with 15% and 30% cement replacement by FBCFA, with the same water-binder ratio of 0.45. Two kinds of fly ash coming from fluid bed combustion in two power plants in Poland have been used.
