This machine is able to produce approximately 500 standard size and shaped blocks in an eight hour day. The interlocking feature on both varieties of ISSB’s helps cut cost on cement. Mortar is only needed on top and bottom of the brick..
When a block is compressed it looses 30% of its volume. This is due to the mechanical compression of the press driving out air pockets and aligning wet clay particles and compacting the clay around the sand particles.
Compressed soil blocks are building blocks formed from stabilized or un-stabilized compressed soil. The compression ranges from several hundred pounds total, to several tons. Because of the great gains in durability un-stabilized blocks are only used where nothing is available to stabilize the blocks. In addition to stabilization, the soil the blocks are to be made from is calibrated for durability, workability, and survivability.
