The material analysed in the present paper is a specific mixture of the shot-earth (named shot-earth 772) produced by introducing, into a high velocity air stream, 7 parts of excavated soil, 7 parts of aggregates and 2 parts of cement (by volume), and by adding about 3% of water (by volume) at the spraying nozzle. The mixture stream is projected at high velocity onto a surface, where the impact compacts the material. A thorough investigation on the microstructural, chemical and physical properties of the shot-earth 772 is performed.
