Comparison of bond stresses of deformed steel bars embedded in two different concrete mixes

Catenary action in a precast concrete building structural system is one of the ways to avoid progressive collapse. The key for catenary action to work successfully depends on the strength performance of longitudinal ties, which closely depends on the bond performance between the ties and concrete. T...

The main objective of the experimental work is to improve the bond performance between deformed steel bar and concrete topping.
