    PRESTRESSING Definition: Pre-stressing is technical process in which internal stresses of structure are introduced so that stresses resulting from external loads are counteracted to a desired degree. In short pre-stressing is counteracting of stresses. History: The concept of prestressing came into action firstly in 1886 by Mr. Jackson of Sanfrancisco, USA.
