The influence of water flow (reversal) on bond strength development in young masonry

摘要

Water loss from the fresh mortar is believed to be related to mortar-brick bond strength development in masonry. Recent research on mortar-brick bond has shown that, particularly, effects of water flow on the composition and the hydration conditions of the mortar-brick interface have to be taken into account to explain bond strength development. However, many cases of unexpected bond behaviour are still registered, and apparently the insight into this complex phenomenon is still incomplete.
