Title: Integral Sodium Chloride Effect on Strength, Water Vapor Transmission, And Efflorescence of Concrete
Author(s): Donald F. Griffin and Robert L. Henry
Publication: Journal Proceedings
Appears on pages(s): 751-772
Abstract:Presents basic data about water vapor permeability of plain concrete and the effects on permeability of certain admixtures such as oleic acid and sodium chloride. Other variables included in the study are: (I) specific location of specimen disk as cut from a concrete cylinder; (2) maximum size of aggregate and (3) environment of specimen whether in 7 3 .4 F , 20 or 50 percent relative humidity. Part of the total study includes the results of a quarter replicate statistical experiment for two levels of each of six factors to permit an analysis of variance of different variables in the permeability study. Salt whisker crystal growth on specimens with sodium chloride as an admixture is discussed. Test results revealed that water vapor transmission values were found to be significantly higher for the higher water-cement-ratio concretes, the absence of sodium chloride, and the presence of smaller aggregate. Origin of concrete disk within cylinder, presence of oleic acid, and relative humidity were factors found to have no statistically significant effect.
