Einkapselung von Altlastenflächen durch Oberflächenzementierung

In the course of soil amelioration, the sealing properties of cement mixtures at depths up to 75 cm in contaminated soil were investigated by analysing soil samples to determine hydraulic and chemical parameters. The influence on the hydraulic conductivity depended on the amount of cement added and the hardening time, with secondary crack formation by normal chemical and physical drying processes. Additional sealing and drainage has to be considered if such a method is to offer a viable alternative. The long-term stability remains to be investigated in greater detail.
