ABSTRACT
Studies on the bond strength between cement mortar and aggregate rock has been reported. However the effects of them on the mechanical behavior of concrete has not been clearified yet. The present paper reports the results of three groups of experiment, that is, (1) the mechanical properties of five types of rock obtained from Kuzuryuu river located at the central part of Japan, (2) their bond strength to the cement mortar and (3) the mechanical behavior of concretes containing each type of aggregate rock.
