Properties of Hardened Concrete
The most important properties of hardened concrete include various strengths, dimension stability, complete stress‐strain relationship, various moduli and Poisson's ratio, and durability. A complete stress‐strain curve of concrete includes the post‐peak response. The 28‐day compressive strength of concrete, determined by a standard uniaxial compression test, is accepted universally as a general concrete property index for structural design. To measure different strengths of concrete, various tests have to be conducted with a universal testing machine. There are two kinds of control methods for strength testing are open‐loop or closed‐loop control. For concrete, shrinkage and creep are the two major phenomena that compromise the dimensional stability. Shrinkage and creep are caused and influenced by many common factors, such as water content, curing conditions, relative humidity, aggregate proportions, and specimen sizes.
