Abstract
Slurry walls have till now been used largely in temporary structures in the construction of retaining walls and underground water screens. But as a result of recent developments in concrete and in the field of excavation equipments it has become possible to construct very deep slurry walls. However, this necessitates development of improved methods of quality control and high strength slurry wall concrete.
This paper describes the research undertaken to study the feasibility of constructing a 2.8m thick and 135m deep slurry wall to serve as a water screen and retaining wall in the artificial island in the Trans-Tokyo Bay Highway project.
To begin with, laboratory studies were carried out to determine the mix proportion of the concrete for adequate flowability, segregation resistance and compressive strength. The results obtained from the laboratory tests were verified in a full scale field test.
