SPECIAL DEVICE AND METHOD FOR CEMENT PRODUCT SURFACE MICROCRYSTALLIZATION
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.
