Abstract : A new polymeric waterproofing material, a fluoropolymer, is mixed with the cement mortar and the properties are investigated. Fluoropolymers are currently being used in textiles industry as fabric protectors and also to impart water repellence properties for textiles. The fluoropolymer used here, perfluroalkylacrylate copolymer, has a chemical structure similar to an acrylic resin. Its action on cement particles is similar to acrylics in that it reacts with cement hydration products, resulting in the formation of bonds between the cement particles and the waterproofing material. The strength parameters, bond strength between the base concrete and the modified cement mortar, water permeability and capillary absorption were determined before and after exposure to UV light and accelerated weathering conditions. The fluoropolymer modified mortar exhibited superior durability parameters than many other commercially available WPMs.
