Abstract：This paper used Kenya volcano cinder as internal curing material,studied the effects of different volcano slag con-tent on the compressive strength of different grade concrete. The results showed that:when the volcano cinder internal curing tech-nology is adopted,the compressive strength of both C40 and C60 concrete at different ages is reduced compared to baseline group, the reducing degree gradually decreases with the extension of the age,even in the later stage,when the volcano slag content is lower,the compressive strength is approximately equal to the reference group,the internal curing water to binder ratio was increased gradually with the increase in volcano cinder addition, while the compressive strength of C40 and C60 was slightly reduced.
