Encapsulation quality of reinforcement: Impact on bond strength and structural design considerations

Conference Dates

September 3-6, 2017


Proper reinforcement encapsulation is a concern among structural engineers who must work with limited specific guidelines for shotcrete. Indeed, imperfections behind reinforcing bars (or any other obstacles) are often reported with the excessive use of set-accelerating admixtures or with unskilled nozzlemen. To address such concerns, past research has mainly focused on optimal mixture consistencies and best nozzle handling techniques to obtain perfect encapsulation [1, 2].
