Concrete blocks are made in various shapes and sizes. Still, the basic principle governing how they're made remains the same: a relatively dry mixture of cement, aggregate, and water is consolidated under pressure in a block press, after which it's left to harden and dry. Once this process is complete, the block is ready for use.

The operation of a block-making machine is based on the vibration and compression of the concrete. They have a hopper in which to receive and store the fresh cement for the production of the blocks. After this, the material is dosed in to fill the mould with the right amounts. To make it easier to fill each mould, the tray and the mould are ...

To make 1:1:2 ratio concrete mix according to volume batching, one should take one bag of cement (35 liters), 1 gauge box of fine aggregate (35 liters) and 2 gauge boxes of fine aggregate (70 liters). If the water-cement ratio is 0.5, then half of the volume of cement which is 25 liters of water should be taken. Fig 1: Gauge Box or Measuring Box.
