Rammed earth bricks -best traditional Green material



Rammed earth is an elderly construction technique. Rammed earth has been around for thousands of years –it was used in construction of THE GREAT CHINA WALL.

If we would like to construct an economic and an eco-friendly construction RAMMED EARTH BRICKS are the best material.

Process of construction of a rammed-earth structure is the same as the last century. Moisture stiff material such as gravel or clay is combined with stabilizing elements such as concrete, it is compressed to form a hard walls and dence. After the construction of rammed earth, you will need to cure for a few months to two years in a humid climate for completely curing.


Ideal material indicating that it is used for the temperature to keep warm the density of rammed earth.

There are some contractors ,who are master in designing homes with the Earth’s minerals.  These types of construction, special care must be taken to adjust the water to prevent the damage seems to be a system that is designed to leverage technology of green next to completely properly, the outflow of water.

A rammed-earth wall involves compressing a damp mixture of earth which has suitable proportions of sand, gravel and clay sometimes with an added stabilizer into an externally supported frame or mould which is used in construction. In past such additives material as lime or animal blood were used to increase stabilization of the material, while in present lime, cement or asphalt emulsions are used. At some places modern material like coloured oxides or other items, such as bottles, tires, or pieces of timber are used.

The construction of an entire wall begins with a temporary formwork, usually made of wood or plywood will act as a mould for the required shape and dimensions of each wall section. The form must be strong and the two opposing wall faces clamped together, to prevent deformation from the large compression forces. Damp material is poured in to a depth of 10 to 25 cm and then compacted to around 50% of its original height.

The material is compressed in batches, gradually building the wall up to the top of the frame. Tamping was historically done by hand with a long ramming pole and was very labour and time consumer while modern construction can be less labour and time consumer by applying pneumatically powered tampers.
