The size of movement depends upon the change in temperature and the coefficient of thermal expansion o f concrete. The coefficient of thermal expansion of concrete is influenced largely by the coefficient of thermal expansion of the aggregates since the aggregate occupies 70-80% of the volume of the concrete.

This type of shrinkage is caused by the loss of moisture from the cement paste constituent, which can shrink by as much as 1% per unit length. Unfortunately, aggregate provides internal restraint that reduces the magnitude of this volume change to about 0.05%.

Nominal Mixes In the past the specifications for concrete prescribed the proportions of cement, fine and coarse aggregates. These mixes of fixed cement-aggregate ratio which ensures adequate strength are termed nominal mixes. These offer simplicity and under normal circumstances, have a margin of strength above that specified.

Water within the hardened cement paste is forced to more as a result of the applied load. This movement of moisture is the primary cause of creep deformation. Some movement also occurs due to the propagation of microcracks. The movement due to creep can be greater than the elastic strain on loading.
