Everywhere in the world and since million years, ground construction was very requested, which is still the case besides today. Indeed, the ground is used in various work for ecological houses for example respectful of the environment. It becomes increasingly used owing to the fact that it not only helps to facilitate work but also to solidify the house.
The construction of the ground walls
The utility of the ground to manufacture walls depends on the matter itself. It should be known that the elements which constitute it have their specificities and can be used according to the needs. They thus should be known so that the construction is well made and which more is in the standards.
In this direction, the ground rich in clay is flexible in wet moulding and the sand spreaders which are more grained are used especially for the compaction in a dry state. It is them which are used for the manufacturing of bricks.
The techniques to set up a ground wall differ from a country but also from an area to another. But in general, the methods resemble each other enough where the first is the cob. It is of a mixture and raw argillaceous ground malaxation. The walls are assembled in layers superimposed for then using a formwork with wood with a thickness which must reach the 60cm. To coat outside by ground so that the walls can breathe must then be done without however painting them.
Then, there is the adobe which wants to say “in block” which consists with the moulding and air drying of brick made up of clay mixed with sand and water with half. There is also the use of vegetable fibers and raw ground brick.
In addition, there are the cover over with soil-straw which is the association of the mixture covers over with soil and straw and called on the formwork. Lastly, there is the cob which is a mixture of fine fiber ground and lime where the use of a concrete-mixer is in this case necessary.
Practical easy ways to perfect construction
The building work of house is not easy tasks with the result that it is necessary to call upon professionals in the field. That is more particularly the case for the raw ground house where it is useful to know the content of clay and all the components of the ground. In the contrary case, its binding property cannot be perceived.
Thus, it is necessary that it is rich in clay with a content going from 15 to 35%. But it is necessary also that it has sand, silt and gravel which are with variable contents. When the material is excavated, the surfacing is not to use owing to the fact that it is impure.
The deep ground is that which corresponds best to this kind of situation where it is necessary to control the granulometric mixture which must be varied. The walls made starting from particles of different sizes are in this more solid case. |
