Soil-Bentonite Slurry Wall Specifications Especificaciones

2017-3-27  SB backfill is usually mixed and placed with earthmoving equipment such as bulldozers and excavators. The typical specification will require that the backfill is mixed “until homogeneous and a slump of 7 to 16 cm is measured”. The slump cone (ASTM D143) is a simple test; after it is performed a few times, a trained operator and slurry specialist can usually begin to assess the proper slump by visual observation. It is more difficult to determine what the term “homogeneous” means for a given project. The mixed SB is usually allowed to contain occasional clods of clay and rocks up to a certain size. All particles should be coated with bentonite
