Effect of Sodium Chloride (Nacl) on Concrete Compressive strength

[1]noted sodium chloride damages concrete while Robertson [2] said sodium chloride accelerates the pigments in the surface of wet concrete immediately after placing. In his research work between 1993 and2005, Carter [3] observed that sodium chloride causes lots more damage to concrete, while Lee, Bonacci and Thomas [4] say that sodium chloride ...

Chloride Binding of Cementitious Materials Exposed to Sodium ...

In this work, chloride-binding isotherms are obtained by testing chloride solutions using a calibrated X-ray fluorescence (XRF) device and were evaluated by comparison with titration. Testing was performed on a cement paste with a water-cement ratio of 0.42, exposed to sodium chloride salt solutions ranging from 0 to 5 mol/L at 23°C.

Concrete degradation - Wikipedia

Chlorides, particularly calcium chloride, have been used to shorten the setting time of concrete. However, calcium chloride and (to a lesser extent) sodium chloride have been shown to leach calcium hydroxide and cause chemical changes in Portland cement, leading to loss of strength, as well as attacking the steel reinforcement present in most ...

Chloride Contamination in Concrete Structures - Wahlen Works ...

Apr 21, 2020 · We talk about chloride contamination frequently because of the damage it can do to concrete that isn’t properly maintained. Chloride contamination comes from rock salt, the primary deicing agent used in Wisconsin. Rock salt is the mineral formed from sodium chloride. WisDOT uses an average of 526,000 tons of rock salt statewide each season.
