This research is devoted to the study of the characteristics of acoustic emission (AE) signals of mortar under uniaxial compression. A total of 40 specimens were tested, in which the water-cement ratio, age, compressive strength and strain were the major parameters of mortar related to the AE signal
The effects of two super water-reducing admixtures on the compressive strengths and elastic moduli of portland cement mortars containing fly ash were determined. The results show that the effectiveness of the chemicals for improving the strengths of mixtures in which portland cement is partially re
