Glass-fibre-reinforced mortar: study of freshbehaviours based on average water filmthickness and fibre/cement ratio [PDF]
Using glass fibres to reinforce cement-based materials (CBMs) has great effects on their fresh behaviours. In addition, the impact of water – particularly the average water film thickness (AWFT) – on the fresh properties of CBMs cannot be ignored ...

Deep Underground Science and Engineering, EarlyView.The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...
