Concrete mixes typically have a fairly high cement content as well as other pozzolana, plasticizers, and chemicals. They also provide 4000-6000 psi strength with a high slump. Advantages of Diaphragm Wall: A diaphragm wall has fewer joints than a secant wall ultimately improves the water tightness of the wall.

Diaphragm walls are rigid reinforced concrete walls made up a number of discrete panels joined together to form a single continuous wall. The rectangular shape of a diaphragm wall is well suited to resist bending and shear forces associated with lateral soil loads which makes them efficient for deeper excavations.

Diaphragm is a member that resists lateral forces and transfers loads to support. Some of the diaphragms are post-tensioned and some contain normal reinforcement. It is needed for lateral stability during erection and for resisting and transferring earthquake loads. Based on past research, diaphragms are ineffective in controlling deflections and reducing …

The diaphragm is an unpaired, dome shaped skeletal muscle that is located in the trunk.It separates the thoracic and abdominal cavities from each other by closing the inferior thoracic aperture. The diaphragm is the primary muscle that is active in inspiration.Contraction of the muscle facilitates expansion of the thoracic cavity.
