Abstract

There is a need to assess the effect of radiation on the behavior of bond strength between steel reinforcement and concrete. However, there is geometrical constraints in the cylindrical capsule which limit the size of concrete samples. Thus, developing a protocol to produce pullout sample and a test setup is needed.

A protocol for fabricating high-precision concrete samples with embedded \#2 steel bar has been developed based on the results of an experimental program. A pullout system has also been developed to investigate the bond activity of concrete and steel. This research looks at two different aggregate sizes 3/8 inch (10 mm) and 1/2 inch (13 mm).

The compressive strength, bond stress, and slip values for concrete with a maximum aggregate size of 1/2 inch (13 mm) are higher than those for concrete with a maximum aggregate size of 3/8 (10 mm), according to the results. Future research should look into the impact of maximum aggregate size on bond activity.
