block vibration molding pressure head is required to exert pressure on the concrete

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 molding block Exert a certain pressure head on the concrete. China Block Asphalt Mixing Plant 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 machine puzzle 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.
