Abstract: The high-frequency vibration nicking device for microbead surfaces includes a high-frequency vibration assembly and a container. Microbeads or mixed materials of the microbeads and a grinding material are filled in the container, and the vibration output end of the high-frequency vibration assembly is connected with the container to perform high-frequency vibration on the microbeads. The high-frequency vibration nicking method for microbead surfaces includes steps of adding the microbeads into the container, turning on the high-frequency vibration assembly, and performing high-frequency vibration motion on the microbeads in the container under the action of the high-frequency vibration assembly. According to the device and the method, the high-frequency vibration assembly generates high-frequency vibration to drive the microbeads to perform high-frequency vibration motion in a limited space, so that mutual collision and friction are generated among the microbeads, between the microbeads and the container wall and between the microbeads and the vibrating body.

Abstract: The invention discloses a special equipment and a method for surface microcrystallization of cementitious materials. The specialized equipment includes a vibrator, a vibration signal generator, a power amplifier and a vibration transmitting body. A signal output terminal of the vibration signal generator is connected to a signal input terminal of the power amplifier, a signal output terminal of the power amplifier is connected to a signal input terminal of the vibrator, the vibrator is connected to the vibration transmitting body, and the vibration transmitting body is to be in contact with the cement product after initial setting. The surface microcrystallization method for cement product: after the casting and before the final setting of the cement product, vibration is applied to its outer or inner surface, the vibration frequency is greater than or equal to 1 KHz, and the vibration time is greater than or equal to 5 minutes. The surface layer of the cement product prepared by the present invention forms a structured layer with a certain thickness, high density, low permeability and relatively uniform surface coverage of granular crystal or gel phase, so that the cement product has excellent anti-aging performance.
