ABSTRACT
This paper will concentrate on soil conditioning with foam for sandy soil.
2 TECHNIQUE FOR SOIL CONDITIONING AND THEIR GOALS
2.1 Technique for soil conditioning
In order to produce foam, water and foaming agent (surfactant) are mixed in defined proportions in a turbulent environment to make a surfactant solution. The surfactant concentration (cf) describes the percentage by mass of surfactant (Qf) in the solution (QL) (water and surfactant) and ranges according to application between 1.5 and 5%. Alternatively to the mass proportions, the volume flows can also be considered with no further conversion factors, because the densities of water and surfactant are approximately equal (Table 1, Eq. 1).
