Abstract
This paper is intended to study the effects of the vibrations on the bond strength when they are applied to the reinforcement of the bentonite suspension. The bond strength of the concrete cast into the bentonite suspension is said to be lower as composed with that of the concrete cast in normal way. But as the results of this experiment, the bond strength of the bentonite concrete to the deformed bars become as heigh as (more than 75% of) the normal concrete when the bars are vibrated during casting. The compressive strength of the bentonite concrete cast with vibration is much the same as that of the bentonite concrete cast with no vibration. But the Young's modulus of the bentonite concrete with vibration is slightly lower than that of the bentonite concrete with no vibration.
