Situ Concrete - an overview | ScienceDirect Topics

The principal advantages of in situ concrete are that it can be cast monolithic, i.e., there are no joints to make good, and the size of members is not limited by capacity of handling equipment. Some of the advantages of precast concrete over in situ concrete are as follows:. Good concrete of uniform quality is more easily obtained under factory conditions.

Prestressed concrete - Designing Buildings Wiki

Prestressed concrete - Designing Buildings Wiki - Share your construction industry knowledge. Prestressed concrete is a structural material that allows for predetermined, engineering stresses to be placed in members to counteract the stresses that occur when they are subject to loading. It combines the high strength compressive properties of concrete with the high tensile strength of steel.
