Appliion of Fly Ash and Slag Generated by Incineration ... · The high slag crushing index of coarse aggregate can result in a limit slag content (20%), and the concrete strength can decrease with increasing slag rate. The lowest concrete strength of less than 30 Mpa appears when the fly ash replacement rate is 40% and the slag replacement rate is 40%. Thus, fly ash and slag cannot completely replace the cement and the coarse aggregate in concrete ...
A Nondestructive EIS Method to Evaluate the Compressive ... · The compressive strength of slagblended cement paste under steam curing was evaluated using a nondestructive electrochemical impedance spectroscopy (EIS) method. In the slagblended cement paste, four slag replacement ratios (0 %, 20 %, 50 %, and 70 %) and two curing conditions (standard curing and steam curing) were employed. The topological structure of the EIS was .
