The utility model discloses a device for measuring chemical shrinkage reaction of a cement material. The device comprises a thermostatic water bath container, chemical shrinkage devices and a camera, wherein the multiple chemical shrinkage devices are fixedly clamped in the thermostatic water bath container in parallel; the chemical shrinkage devices comprise reaction bottles and transfer pipettes; the reaction bottles are soaked in the thermostatic water bath container; cement samples and deionized water are mixed inside the reaction bottles by virtue of temperature preservation of the water bath; the transfer pipettes are inserted into the reaction bottles by virtue of rubber plugs; one end of each transfer pipette is communicated with the deionized water, and the other end of each transfer pipette is communicated with atmosphere; a section of colored oil is on the liquid level of the deionized water in the transfer pipettes; scales are arranged on the transfer pipettes; the camera faces the transfer pipettes; and the shooting area comprises one part of the transfer pipettes filled with the oil. According to the device disclosed by the utility model, the change conditions of the chemical shrinkage reaction of the cement can be recorded in real time in an all-weather manner, and the device is convenient to record and easy to operate. Moreover, the recording is accurate compared with manual operation, the later-stage review data determination is conveniently realized, an illumination device is arranged, and uninterrupted records can be realized at night.
