Diaphragm wall thickness
WebDiaphragm Wall is generally reinforced concrete wall constructed in the ground using Under slurry technique which was developed in Europe. The technique involves excavating a narrow trench that is kept full of an engineered fluid of slurry. Walls of thickness between 300 and 1200 mm can be formed in this way up to a depths of 45 meters.

WebAccording to the American Concrete Institute’s ACI 318, Section 12.3, diaphragms must have sufficient thickness so that all applicable strength and serviceability requirements are satisfied. Usually, the thickness of a floor or roof system is determined first based on the strength and serviceability requirements pertaining to gravity loads. WebTypically, the wall thickness for injection molding is 2–3 mm. It is important to have constant wall thickness in the part. If thicker sections are required, then it is important to have transitions from thick to thin regions. The thicker regions can have gentle and no sharp transitions as shown in Fig. 18.12.
