Characterization of compacted land for use in construction.
The land has been used to build buildings for centuries. Today, it is estimated that half of the world’s population, about three billion people, on six continents, live or work in land-built buildings.
Compacted earth is an ecological building material that has inherent environmental benefits:
It is not manufactured or transported.
A wall made of compacted earth serves as a natural insulator, being warm in winter and cool in summer.
When the building is demolished, the land returns to the ground and can be recycled indefinitely.
However, mineralogical composition, among other properties, plays an important role in the final performance of this building material.
Consequently, X-ray diffraction is able to respond/control the quality or feasibility of land use as building material by identifying and quantifying its mineralogical composition (crystalline and aefa).
