The utility model provides a concrete vibro consistence instrument. The concrete vibro consistence instrument comprises a container, a vibrating table, a disc, a timing display, a pit, a pore channel,a piezoelectric wafer, a fuse and a timing module, the container is fixedly arranged on the vibration table and is used for containing a cement concrete mixture to be detected; a plurality of pits are evenly distributed in the lower surface of the disc, hole channels communicated with the upper surface are formed in the bottoms of the pits, and the disc is matched with the container. A timing display is fixedly arranged on the disc and comprises piezoelectric wafers, fuses and timing modules, the piezoelectric wafers and the hole channels are arranged at the upper ends of the hole channels ina one-to-one correspondence mode, and all the piezoelectric wafers are connected in series and then connected with the fuses and the timing modules in series to form a detection loop. The problem ofmanual timing is effectively solved, the effect of automation can be achieved, the experiment efficiency is improved, the time is read through a closed circuit, the influence of human factors is reduced to a large extent, and then the accuracy of detection data is guaranteed.
