Wire Cut Bricks Compressive Strength

Wire Cut Bricks Manufacturing Process:

Wire cut bricks are another type of clay bricks by slicing a brick-sized piece from a bulk mould of clay using a wire tool. After the clay is formed into a large, rectangular piece of material, it is sliced into several brick-sized pieces by pushing wires through the material. A rough surface, created during the slicing procedure of wire-cut bricks is produced through the stretching of the clay as the wire is pushed and forced through the clay mould. The cutting of the clay using wire tools in wire-cut bricks makes a telltale sign in the curved surface of the brick that renders them easily recognizable. Most wire-cut bricks are formed as a large block of brick material and pushed through a die onto a cutting table. After it is pushed through the sizing die, the block is sliced into several brick pieces by forcing a large cutter tool through the block of material.

When the bricks are sliced by the wire, it pulls the edge of the brick, stressing the clay and creating small cracks in the surface of the stretched material. As the wire-cut bricks are fired, a process that heats the bricks, the moisture in the clay is baked out and the molecules of clay heat together and strengthen into a long-lasting building product. The stretch marks on the surface of the baked brick separate into rough cracks and crevasses and this feature are what gives the bricks the visual appeal that many builders and homeowners seek in a finished appearance.

Besides producing a cost-effective product, the wire-cut bricks require much less time to be manufactured than Table Mould Brick. A typical block of clay will produce six to nine bricks once cut and cured.  The whole process will need maximum five people team typically to manufacture bricks with a single brick-making machine. Two people load the clay brick material into the hopper of the machine and add the appropriate amount of water to the mix. Another person pushes the material into the shaping chamber and forces the brick material out of the forming die and onto the cutting table. Finally, the wire-cut bricks are sliced using the wire tool by a fourth worker and the fifth worker shifts the bricks from the cutting table onto a drying rack.
