This study investigated the damping properties of preplaced concrete with W/C and coarse aggregate size was . Experimental results show that the damping ratio of the C40 is 2.63%, which is 1.72 times higher than the damping ratio of the C30 of 1.53%. The higher the water cement ratio, the higher the damping ratio is. In addition, the damping ratio of the C-PA series is reduced by 17% to 60% as compared with the C-series. The difference of the damping ratio due to the coarse aggregate size in the C-PA series was found to be within the standard deviation
