Modified hardening slurry for installation of steel piles
L. Rafalski

conventional steel I-beam piles are most often driven in the ground to construct the Berlinoise structure. On the Warsaw Underground construction sites steel piles were placed in holes bored in the ground to reduce the influence of vibration on surrounding buildings. A hardening slurry was employed to protect the stability of a hole during the process of boring. After setting, the slurry bond a pile with the ground and ensured a proper structure. The paper describes the design procedure of hardening slurry composition resulting from the boring method, structural parameters of a pile and necessity of its recovery. To obtain the slurry of suitable physical and mechanical properties, a modifier was applied. It was implemented as a component of the slurry and proved significant for installation of steel piles. The paper mentions also of site investigations concerned with application of the hardening slurry and including steel piles tests that were carried out in a full scale.
