Book Description
Because of its low resistance to tensile or elongating forces, plain and normally reinforced concrete cracks at quite low loads when subjected to increasing amounts of tension whether induced directly or by bending. In order to oppose such tensions, and thereby to resist cracking, a concrete member may be deliberately subjected to a prior compression, or precompression, applied uniformly or otherwise over its section. Such precompression, usually applied before there are any service loads, is termed prestressing, and the member is termed a prestressed concrete one. This Note, which replaces the earlier Note NSB No. 50, describes the principles of prestressing as applied to concrete against the background of current practice.

Book Description
The loss of prestress resulting from creep and shrinkage in concrete was investigated for concrete specime * ns made with Type I portland cement and with Type III portland cement.Forty-nine sets of specimens were fabricated and tested; each set consisted of a prestressed specimen and an otherwise identical companion specimen without reinforcement. The length changes with time were observed at intervals up to an age of 500 days.These observations were made for concretes subjected to different levels of prestress, and for concretes prestressed at different ages.Length changes in nonreinforced companion specimens were also obtained. Thus this study is concerned with elastic deformation occurring at time of stress transfer, shrinkage or swelling, and creep.(Author).
