Explain the term - Prestressing Force
Due to the stretching of tendons, tensile stresses develop inside tendons. Resultant prestressing force in tendons may be calculated by multiplying these tensile stresses to the cross-sectional area of tendons. When this tensile prestressing force of tendons is transferred to concrete, it produces equal compression in concrete.
Level 2 Acceptance Testing : This will also include the same tests as in Level 1 A. General inspection B. Test on specially moulded test piece C. Test on complete bearings
