That way, they can be properly treated to produce a structurally stable base for construction operations to build upon. Annually, billions of dollars are spent worldwide in repairing the severe damage that currently affects constructions as a result of the swell phenomenon. The swelling phenomenon of soil occurs progressively and depends on the soil saturation and its clay structure (Medjnoun et al., 2014). Expansive Soil And Foundation Cracks Video. The two cases do not have the same swelling rate or the same behaviour. (PDF) Identification of expansive soils - ResearchGate Financial Support from IIT Kharagpur is gratefully acknowledged.

(A) Sand and an expansive soil S1 inside the oedometer ring. The validation of the suggested method of classification needs, first, the collection of a big number of oedometer data, for expansive and non-expansive soils from different case histories. As shown in Figure 7B, the compression index Cc and the swelling index Cs are determined from the oedometer curve. Oedometer cell with displacement sensor. Expansive Soils and Construction Implications | EDT Forensic *Note - Expansive soils are known to expand to 10% or more (and this is not uncommon). Expansive soils are present throughout the world and are known in every US state. The latter affects the distribution of internal stresses between the soil particles (Kehew, 1995). The damage done by expansive soils is then attributed to poor construction practices or a misconception that all buildings experience this type of damage as they age. The existence of swelling soils can lead to slope instability, a differential heave buckling of pavement, a differential settlement of roads or railways, retaining walls buckling (Figures 3A,B), tunnels collapsing, and damages to retaining walls.
