Pressurization of concrete mixture

According concrete mixture by vibrations when a thixotropic phenomenon can be relatively small Pressure to obtain dense short time, so that the required pressure vibration precast concrete plant Exert a certain pressure head on the concrete. China Block Making Machine standard indenter right Block upper surface pressure value should be greater than 0.02Mpa, foreign to the dry concrete mix And material pressurized value of approximately 0.015 Mpa, too much pressure will prevent concrete mixing Granule material vibration, impact block density results. Pressure values according to the above,Concrete mixing plants Weight block forming machine head pressure produced to meet the requirements, in particular in pressure head Is set on the vibrator, the vibration compacting effect is better than static.
