The value of Poisson's ratio of concrete is 0.2.
Poisson’s ratio of concrete is the ratio of transverse strain to longitudinal strain in a concrete specimen subjected to axial loads. The longitudinal strain and vertical strain are produced due to concrete volume reduction under compression load. Volume reduction of the concrete specimens is the result of crushing small aggregate sizes due to exerted loads. Poisson’s ratio of concrete is a constant for determining the stress and deflection properties of structures such as beams, plates, and shells

Poisson's ratio of concrete
Poisson's ratio is the ratio of lateral strain to the corresponding axial strain for a material that is being compressed or stretched. Poisson's ratio is a fundamental property of any material and varies depending on the type of material.
Value of Poisson's ratio of concrete
The value of Poisson's ratio of concrete is 0.2. This means that for every unit increase in length of concrete, its width decreases by 0.2 units.
Explanation
Concrete is a composite material made up of cement, aggregates, and water. It is a brittle material that is strong in compression but weak in tension. When concrete is subjected to compression, it tends to expand laterally. The Poisson's ratio of concrete determines the extent of lateral expansion that takes place when concrete is subjected to compression.
The value of Poisson's ratio of concrete is relatively low compared to other materials. This is because concrete is a brittle material and does not undergo significant lateral expansion when subjected to compression. The low Poisson's ratio of concrete makes it suitable for use in construction as it has good stability and can withstand heavy loads.
Conclusion
In summary, the value of Poisson's ratio of concrete is 0.2. This property of concrete determines the extent of lateral expansion that takes place when concrete is subjected to compression. The low Poisson's ratio of concrete makes it a suitable material for use in construction.
