The project aims to develop, optimize, and improve a sustainable technology that can be applied in the construction sector, both for civil and industrial buildings. This technique, named “Shot-Earth” consists in a mixture made of soil, aggregates, and a binder (if needed), blended together by means of the proper quantity of water. It can be used to build beams, walls, slabs, and vaults, for example. If properly reinforced, these elements have adequate load-bearing functions which characterize structural components. In addition, layers of Shot- Earth can be placed as external coatings to guarantee improved levels of insulation.
The peculiar feature of this technique is the technology behind the new constituent, which allows to lay the material on the formworks or on the surfaces to be insulated. To this aim, in fact, a spraying procedure through a pressure pipe is used. This practice is characterized by some advantages with respect to traditional processes. For instance, it can overcome the restriction of fixed shapes and deal with more complex geometries such as in vaults and shells. Furthermore, the high-pressure spray phase limits the compacting operations by means of vibrating device and the use of supports during the material jetting.
