C-S-H seed crystal preparation device

The utility model provides a C-S-H seed crystal preparation device. The device comprises a water bath box, a three-necked flask and a stirring rod, the water bath box is placed on the base, a three-necked flask is arranged in the water bath box, a stirring rod is arranged at a middle bottle opening of the three-necked flask, the upper end of the stirring rod is connected with a motor for control, the motor is arranged on a fixing frame, and the fixing frame is connected with the base through an iron rod support. According to the utility model, the particle size of a compound reaches an ideal state through stirring of the motor, chemical reaction is uniform, particles are prevented from being agglomerated and adsorbed, precipitation is avoided, a dispersing agent is added to control the particle size of the particles, and the nano-composite C-S-H seed crystal is prepared. In the process of preparing the nano C-S-H seed crystal by using the device, the nano C-S-H seed crystal nucleating agent with good dispersi
