Explanation: High tensile steel are commonly used in prestressed concrete members and ultimate strength of high tensile steel is equal to 2100n/mm2, therefore the losses of prestress due to shrinkage and creep with a stress of 200n/mm2 are restricted. The C-S-H is strongly hydrophilic, and has a colloidal microstructure disordered from a few nanometers up. are responsible for losses of grains. The principle behind prestressed concrete is that compressive stresses induced by high-strength steel tendons in a concrete member before loads are applied will balance the tensile stresses imposed in the member during service. Therefore high tensile steel is made for prestress concrete. Q:Are imperfections in solids beneficial or harmful?

The member shortens due to the force and this relieves some of the prestress; The concrete shrinks as it further cures. What are the different types of pre tensioning losses and post tensioning losses? Relaxation of stress in steel. So the loss in prestress occurs due to friction between the concrete surface and the tendon in the process of tensioning. Also, hard, dense aggregates that are not absorptive and have a high modulus of elasticity are desirable for low shrinkage and creep rates.

Median response time is 34 minutes for paid subscribers and may be longer for promotional offers. Prestressing is the process of introducing compressive stress to the concrete to counteract the tensile stresses resulting from an applied load. Answer (1 of 2): Why do losses occur in a prestress structure? : to introduce internal stresses into (something, such as a structural beam) to counteract the stresses that will result from applied load (as in incorporating cables under tension in concrete). Creep resistance is a term used in materials science that refers to a solid material's ability to resist creep, which refers to the tendency of a material to slowly deform over a long period of exposure to high levels of stress. The prestress loss due to elastic shortening in pretensioned members is taken as the concrete stress at the centroid of the prestressing steel at transfer, f cgp, multiplied by the ratio of the modulus of elasticities of the prestressing steel and the concrete at transfer.
