Chapter 6. Strength of concrete
Strength of concrete is commonly considered its most valuable property, although, in many practical cases, other characteristics, such as durability and permeability, may in fact be more important. Nevertheless, strength usually gives an overall picture of the quality of concrete because strength is directly related to the structure of the hydrated cement paste. Moreover, the strength of concrete is almost invariably a vital element of structural design and is specified for compliance purposes.
The mechanical strength of cement gel was discussed on p. 34; in this chapter some empirical relations concerning the strength of concrete will be discussed.
In engineering practice, the strength of concrete ...
