What are the various durability tests on concrete? Quora

The durability tests you will need to perform will depend on the exposure conditions and the materials characteristics. For example, some answers already suggested the rapid chloride permeability test, which you will only use in cases where your concrete is exposed to a source of chlorides (de-icing salts or marine exposure).

Testing the Quality and Durability of Concrete in Seconds

Multiple tests for obtaining and understanding concrete durability by measuring its ability to resist chloride penetration have widely become accepted. This method, commonly known as RCPT (rapid chloride permeability test), measures chloride penetration on a range from high to negligible and is standardized by ASTM C1202: Standard Test Method for Electrical Indication of Concrete’s Ability

Durability of Concrete Factor Affecting Durable Concrete

Durability of concrete normally refers to the duration of a life span of the trouble-free performance of concrete. Different types of concrete require different degrees of durability depending on the exposure environment and properties desired. For example, concrete exposed to tidal seawater conditions will have different requirements than indoor concrete in dry areas.

DURABILITY ASPECTS OF STANDARD CONCRETE

improve concrete durability and strength, especially where high early age curing temperatures occur. High replacement levels of fly ash are uncommon however, because of resistance to change by the cement industry and because of concerns about the early-age strength and the quality of concretes produced with high cement replacement levels. Kevin Smith et al. (2004) established a testing regime

Testing concrete mix to predict durability Construction

Concrete’s permeability is a good indicator of its quality and durability, but it is not all that is needed to determine an accurate conclusion regarding the durability of a concrete mix. It is not always enough for concrete to feature low permeability. Durable concrete is relatively impermeable as long as it remains un-cracked. The tendency of concrete to crack plays a significant role in
