Project description

Low load-bearing soils – that is, loose rocks at the Earth's surface – often receive soil treatment with lime or cement in road construction and civil engineering. Such stabilization measures can, however, lead to the formation of the minerals ettringite and thaumasite when dealing with sulfate and/or aluminum silicate containing earth materials. The associated volume increase can cause ground uplift or destabilization of a transport route (e.g. motorway A71, AS Sömmerda East, connection B85, 2014). The foundational knowledge relevant to the construction materials sector is largely known by now, but is not always adequately taken into account – partly due to the great variability of natural materials and also as a result of their properties. Thus, there is currently a need for research in the form of experimental investigations.

The aim of the project is to capture and characterize the interaction of defined graded binder mixtures used in soil improvements with a practically selected real soil. These results are interpreted in terms of their damage potential for the specific investigation and evaluated in relation to practical requirements.
