Viscosity analysis of lightweight foamed mortar for foam stability

기포 안정성 확보를 위한 경향 기포 모르타르의 점도 분석

In this study, viscosity analysis of the lightweight foamed mortar was conducted to evaluate the foam stability. According to a series of experiment, void volume related with density of the mixture and viscosity of the mixture were infleunced by water-to-binder ratio and addition of viscosity modifying admixture (VMA). Especially, the stability of the foam inside the mortar was confirmed with adding VMA.
