Deformations of concrete arise up at hardening, exploitation and test of

concrete.

Two kinds of deformations of concrete are:

1. Deformations due to applied external loads (power deformations);

2. Deformations due to volume changes under influencing of changes in

temperature and moisture content (own deformations).

5.1. Concrete deformations at short-term load

Concrete Performance in constructions is determined by elastic and plastic

deformations.

Complete deformation of concrete at a definite age of hardening (ετ) is

calculated by the equation:

ε = ε + ε + ε
