The quality of concrete is measured byStrength DurabilityDimensional Stability

§4.4.1 §4.4.1 QUALITY OF CONQUALITY OF CONCCRERETTEE

Hardened concrete must have sufficient strength to resist stresses from loads on a structure.

The strength must also be high enough for variations in concrete mixtures.

Strength

QUALITY OF CONCRETE

Concrete must be able to withstand forces of deterioration such as : Freezing and Thawing Wetting and Drying Erosion and Chemical attack

Durability

QUALITY OF CONCRETE

Qualified concrete should have a minimum of shrinkage or expansion because of outside forces and chemical reactions within the concrete itself.
