Title: Investigating Salt Frost Scaling by using Statistical Methods
Author(s): Marianne Tange Hasholt, Line H. Clemmensen
Appears on pages(s): 1-16
Keywords: Salt frost scaling, frost resistance, mix design, air void structure, ANOVA, regression.
Abstract:A large data set comprising data for 118 concrete mixes on mix design, air void structure, and the outcome of freeze/thaw testing according to SS 13 72 44 has been analysed by use of statistical methods. The results show that with regard to mix composition, the most important parameter is the equivalent water to cement ratio (w/ceq). Regarding the importance of the air void structure, the most important parameter turned out to be the total surface area of air voids. The impact of this parameter is statistically more significant than the impact of the spacing factor, and it raises the question if total surface area of air voids is a more appropriate evaluation criterion than the spacing factor, which is normally used.
