Answer: The strength should be considered as the most important property of concrete. It has the same properties as natural stone: excellent resistance to compression than tension. As a consequence, the criterion of strength is considered to be the tensile strength of concrete in compression.
For example the strength of concrete M150 and other brands is growing as a result of the interaction of cement with water. The normal interaction is possible only in warm and humid conditions. The same interaction of cement with water can completely stop if concrete dries or freezes. It can be concluded that the early drying or freezing of the concrete irreparably affects its structure and properties.
