Web− General construction backfill and void filling − Utility trench backfill and conduit bedding materials − − Structural fill The desired engineering and performance properties of CLSM vary with the application. For example, it may be desirable for utility trench backfill material to be excavatable and permeable to ground water and Webm/sec., a 10% increase in flow rate results in a 21% increase in the hydraulic fill pressure gradi-ent, but only a 1% increase in the paste fill pres-sure gradient. This has a marked bearing on the stability of the operating point as discussed later in the section on hydraulic design of backfill distribu-tion systems. LAMINAR FLOW SETTLING
