Concrete mixture by vibrations when a thixotropic phenomenon

 Concrete mixture according to the thixotropic effect to vibration phenomenon, can be relatively small pressure, the shorter time to obtain dense, so block vibration molding pressure head required to exert pressure on the concrete. Concrete block machine standard indenter pressure on the upper surface of block value should be greater than 0.02Mpa, foreign to the dry concrete mixes pressurized value of approximately 0.015Mpa, too much pressure will prevent the concrete mixture granule vibration, concrete block making machine ensity results. Pressurizing the above value, the general block machine head pressure produced to meet weight requirements, particularly the pressure head is set in the vibrator, the vibration compacting effect is better than static.
