DURABILITY OF CONCRETE

DURABILITY OF CONCRETE

Durability of concrete is its capacity to resist its disintegration and properties. The concrete should be resistant to environmental conditions, wear and other destructive agencies.

Durability is influenced by concrete permeability to water and other potentially deleterious materials. Durability can be measured using different methods and considering various factors or properties of concrete and thus each method corresponds to some measurable properties of concrete. Bulleted below are some properties of concrete that are used in measuring durability of concrete.

Measurement of durability:

use of performance test of service records bleeding rate (a measure of permeability)water tightness (a measure of impermeability) volume changes on setting,wetting and drying,Properties of concrete that are used in measuring durability of concrete

freezing and thawing,heating and coolingchemical deteriorationerosion and resistance to wearcreep (change in length of concrete under stress
