Vibration Compaction Technology
Contents |
[edit] Introduction
Vibration compaction is one of the methods of manufacturing products from a concrete mix. This technology provides for the compaction of concrete mixtures through the combination of vibration and simultaneous pressure from above.
[edit] Using vibration compaction
For this manufacturing method, semi-dry hard concrete mixtures are used. Such a mixture has a smaller amount of water compared to the mobile mixture, which makes it less ductile.
For moulding by vibration compaction, the plasticity should be P1 with a cone slump of 1 – 4 cm. After completion of compaction, the mould is removed, and the product must continue to maintain its dimensions and appearance.
It is the rigidity of the mixture that ensures the filling of the mould under the action of vibration and its own mass. The traditional technology of vibration compaction involves moulding using deep vibrators. However, there are restrictions on the size of manufactured products.
[edit] Machine made concrete blocks
The process of making concrete block using machines consists of several steps. Concrete mixture is fed into the receiving hopper. Then the mould is filled with a mixture. Mounting loops are mounted in the locking device for moulding and electric vibrators are used to mould the block directly. The process takes approximately three to four minutes.
The technology of vibration compaction and the mobility of the concrete block making machines makes it possible to produce up to 120 blocks per shift.
