Although the constituents of concrete (aggregate and hydrated cement paste) behave in a linear elastic manner if stress is applied to them and the resulting strain is measured, concrete is not a linear elastic material throughout its entire stress-strain curve. What is the main reason for the deviation from this behavior?
