We have already had few ideas about disintegration of concrete associated with ice removal agents. In this post we will finish this topic. We were on Klieger and Verbeck’s observations. Here we will learn about other observations that can conclude our idea about concentration and types of salt that produce most harm to concrete.
Cady and Brown (1975) also found similar results as discussed in previous posts, i.e. intermediate concentration results most severe disintegration of surface.
Litvan in 1975 and 1976 also sought results consistent with other two observations. But he had added some extra conclusion which is ice removal agent results high degree of saturation in concrete. He furnished that this is the main cause of detrimental effect.
At a particular temperature of concrete , salt solution in ice removal agents produce a vapor pressure than that of water i.e. little or almost no drying is observed between wetting and cooling cycles.
Dear reader ASTM C672 provides determination procedure to assess resistance of a particular mix against scaling under application of ice removal agents. In our upcoming post we will discuss this procedure.
