Rapid Chloride Permeability Test (RCPT) was carried out to assess resistance of concrete against chloride ingress. Also, specimens were submerged in 3% NaCl solution of temperature 60 o C for 6 Chloride Resistance of Concrete Figure Variation of porosity with depth of concrete slabs cured using different methods (Gowripalan et al 5) The porosity or permeability of insitu concrete is highly dependent on the degrees of compaction and curing during placing and the early life of.

testing the resistance of concrete to chloride ingress, the European Commission funded the research project CHLORTEST, in which 17 partners from 10 European countries participated.

Chloride ingress into concrete involves complex physical and chemical processes. The complexity comes at least from three sources: a) The external environment is not File Size: 2MB. Chloride ingress in reinforced concrete induces corrosion and consequent spilling and structural weakness, and it occurs world-wide and imposes an enormous cost.

Yet it can be resisted by using test methods and relevant models for service life prediction. Resistance of Concrete to Chloride Ingress sets out current understanding of chloride transport mechanisms, test methods and prediction by:   In cold climates, reinforced concrete structures (RCSs) are frequently and severely damaged by freeze–thaw (FT) and deicing-salt attack during winter periods.

FT action can also cause additional water uptake known as frost suction. If a critical degree of water saturation is exceeded, severe deterioration of the microstructure of the concrete is likely, enhancing chloride ingress and Cited by: concrete, and some physical effects, such as frost attack, can be greatly reduced by reducing the permeability of concrete.

As the permeation of concrete decreases, its durability, in terms of physico-chemical degradation, increases. Reinforced concrete structures exposed to. Keywords: chloride resistance, transport mechanism, test methods, diffusion, coefficient.

Date: 6/1/ Abstract: This report discusses the various factors affecting chloride resistance of concrete, mechanisms of chloride transport, related test methods and performance specifications. This paper presents analysis and evaluation of experimental results of chloride ingress and chloride-induced corrosion resistance of concrete made with Portland limestone cement (PLC).

The results were mined from globally published studies from 32 countries sinceyielding a matrix of 20 data by: 1. Steel in concrete can be protected from corrosion in three main ways: (1) seal the surface of the concrete to minimize the ingress of chloride ions, carbon dioxides, and water, (2) modify the concrete to reduce its permeability, and (3) protect the reinforcing bars to reduce the effects of chlorides and carbon dioxide when they do reach the steel.

Based on the results, it was concluded that chloride diffusion in concrete was independent of either crack width or the crack wall roughness for the ranges studied. The transecting, parallel-wall cracks were found to behave like a free concrete surface, resulting in a case of two-dimensional diffusion and greatly promoting chloride ingress.

Changes in the salt attack resistance of concrete using ground granulated blast furnace slag (GGBFS) were examined based on different curing conditions.

These conditions were divided into air and underwater curing. Three concrete mixes with GGBFS replacement ratios of 0% (control group), 30% and 60% were fabricated.

AASHTO T Standard Method of Test for Resistance of Concrete to Chloride Ion Penetration (Salt Ponding Test) The AASHTO T test (commonly referred to as the salt ponding test) is a long- term test for measuring the penetration of chloride into concrete.

The test requires three slabs at least 75 mm thickFile Size: KB.The addition of SCMs to concrete can substantially increase the concrete's resistance to chloride ingress.

The SCMs most commonly used in concrete exposed to chlorides are fly ash, slag, SF, and metakaolin. The use of SCMs can improve concrete's durability, resistance to degradation due to multiple mechanisms, and strength gain by: 5.Buy Resistance of Concrete to Chloride Ingress: Testing and Modelling 1 by Luping Tang, Lars-Olof Nilsson, P A Muhammed Basheer (ISBN: ) from Amazon's Book Store.
