Title: Action Mechanisms And Performances Of Hydrophobizing Additives In Mortars
Author(s): Alberto Lagazzo; Silvia Vicini; Angelo Nora; Rodolfo Botter
Publication: Special Publication
Appears on pages(s): 16.1-16.10
Keywords: fatty acid soaps; mortar durability; hydrophobicity; salt oleate; salt stearate; porosity
Abstract:Metallic soaps are salts from long chain fatty acids and they are popular as waterproofing due to their low cost and effectiveness.
A detailed investigation on the mortar specimens made with different chemical additives based on Na oleate, Ca stearate – Na oleate, Al stearate and Ca - Na laurate has been performed.
The additives analyzed present a different mechanism of action: Na oleate has a strong effect on the development of mortar microstructure while Al stearate or Ca - Na laurate leaves the microstructure very similar to that of the reference samples. The experimental evidences, by measuring the porosity, the water absorption, the mechanical properties and the morphology, confirm these internal structures in the mortars.
