Water Absorption Test. It normally refers to the duration or life span of trouble-free performance.

This article is based on the authors’ “Acceptance Criteria for Durability Tests,” published in the Winter 2007 edition of Concrete inFocus, National Ready Mixed Concrete Association, pp. Various tests have been developed around the world for concrete durability quality control testing. Concrete is a durable material. 41-53. 5. However, not all of these tests can be carried out by testing agencies throughout the world. Description: The Rapid Chloride Permeability (RCP) test is an electrical test used to estimate the durability of concrete.Test methods – like ASTM 1202, Standard Test Method for Electrical Indication of Concrete’s Ability to Resist Chloride Ion Penetration – monitor the amount of electrical charge passed through cylindrical specimens for six hours. Durability is defined as the capability of concrete to resist weathering action, chemical attack and abrasion while maintaining its desired engineering properties. This test does have various drawbacks that make it unreliable, especially for the comparison of different mix designs or for evaluating concrete durability. The durability of concrete is defined by the ability of concrete to resist weathering action, and chemical attack while maintaining it’s desired, engineering properties. Here is the other test that would determine the durability of concrete. Durability of concrete is determined by its ability to resist weathering action, chemical attack, abrasion, or any other process of deterioration, and will retain its original form, quality, and serviceability when exposed to its environment. 1: ASTM C 1202 (RCP) test setup and suggested qualitative indicators in the test method 3% NaCl 0.3N NaOH 60V Concrete Cylinder - + However, due to the use of inappropriate materials, poor construction practicing, insufficient curing, and improper mix designs, many structures show premature and serious deterioration. Durable concrete is a result of proper design, proportioning, placement, finishing, testing, inspection, and curing. Rapid Chloride Permeability test. Concrete testing program. The RCP test should not be used to accurately determine the permeability of a concrete mix containing supplementary cementitious materials or chemical admixtures. The three cube sample shall be taken from the delivered fresh concrete and kept it in the curing tank for 28 days or after 24 hours the concrete sample would be demoulded and it will be sent directly to the approved third-party laboratory to ensure its curing. Limitations. Fig. Different concretes require different degrees of durability depending on the exposure environment and properties desired. A durability test was required that would be simple to conduct and could be performed in a short time by local testing agencies.
