Creep can be defined as the elastic and long-term deformation of concrete under a continuous load. Generally, a long term pressure changes the shape of concrete structure and the deformation occurs along the direction of the applied load. When the continuous load is removed, the strain is decreased immediately. The amount of the decreased strain is equal to the elastic strain at the given age ...

Some admixtures may also affects cracking because of their effects on such contributory factors as rate of hardening, shrinkage, and creep. There are ten ways to help keep down cracking. (1) Design the structure with a mind to the degree of restraint during drying or cooling of the concrete. (2) Prestress wherever feasible. (3) Provide competent inspection, and back it up. (4) Use materials ...
