Compressed Earth Block
Compressed earth blocks (CEBs) are earthen bricks compressed with hand-operated or motorized hydraulic machines. Stabilizers such as cement, gypsum, lime, bitumen, etc. are used during production or on the surface of the bricks.
Advantages of CEB:
• Uniform building component sizes, which result in faster construction.
• Use of locally available materials and reduction of transportation
• Modular elements like sheet-metal roofing, and pre-cast concrete door/window frames can be easily integrated
into a CEB structure.
• The use of locally available materials and manpowerhelps in improving local economy rather than spending for procuring building materials from a distant place.
• The earth used is generally subsoil and thus the top agricultural soil remains intact.
• The reduction of transportation requirement can also make CEB more environment-friendly than other materials.
• CO2 emission is practically nil in the production of CEBs.
• If the wet compressive strength is more than 20 kg per sq. cm, then a RCC roof can be laid and a second storey can be built. If the blocks have more than 8% cement stabilization, then a three-storey, loadbearing structure can be built.
• Good quality blocks having lesser water absorption can safely be used in areas with high rainfall.
