Air voids, an important component of concrete, are dispersed uniformly throughout the concrete to improve durability and workability. Air voids improve durability by increasing freeze-thaw and scaling resistance. Air
voids improve workability by reducing bleeding and segregation.
Testing is often conducted to determine the amount of chloride ions (typically from deicing salts) on the surface of the damaged concrete.
Unexplained cracking often requires a visual inspection or sampling of cores to determine potential causes.
Concrete hydration occurs when the paste hardens and gains strength. The degree of hydration is dependent on curing temperature, age, curing conditions (available of water), and water-cement ratio of the concrete.
Carbonation is a type of concrete distress that occurs when carbon dioxide from the air interacts with the concrete resulting in a reduction the pH of the concrete
The water-cement (w/c) ratio of concrete is a large indicator of compressive strength and durability.
Often determining the quality of the concrete and potential causes of concrete distress requires a full petrographic examination, combination of petrographic techniques. This technique can include macroscopic testing, microscopic testing, and/or chemical testing.
