Question

Explain the mechanism of shrinkage and the factors affecting the same.

Answer 1

Answer:

Creep is time dependent deformations of concrete under permanent loads (self weight), PT forces and permanent displacement.  When concrete is subjected to compressive loading it deforms instantaneously.This immediate deformation is called instantaneous strain. Now, if the load is maintained for a considerable period of time, concrete undergoes additional deformations even without any increase in the load.This time-dependent strain is termed as creep
