M7M2 Hydraform compressed earth block machine

Hydraform compressed earth block machine M7M2  is a special equipment for producing clay interlocking brick by cement, clay, sand, fly ash, quarry dust and other materials. after curing, the blocks can be interlocked tgether without mortar. The blocks interlock each other from front and back, top and bottom 4 directions. Hydraform compressed earth block saves time and cost of buildings.

M7A2  can be powered by a diesel engine or an electric motor. also can be towed to anywhere needs blocks by truck , and saves the transportion cost of raw materials and blocks.

A interlocking block is produced from a soil and cement mixture.

The soil type is classified as a sandy – loam. The soil should contain

more sand than clay and silt (fines). If the clay content is too high, sand

will need to be blended in with the soil.

The clay keeps the block together so it is easy to carry the block

during block-making. The sandy portion is what binds with the cement to

give the block its ultimate strength.

Too little clay will make block handling difficult, too much clay will

make the block shrink and crack during curing.

interlocking blocks are made from sub-soil 1 meter below ground

level, never top soil, which contains organic material
