§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.
Dimensional stability
