  • Influence of air entraining agent on bond improvement in cementitious mortars reinforced with continuous carbon filaments [Elektronski vir]
    Ivanič, Andrej ; Lubej, Samo, 1958- ; Anžel, Ivan, inženir metalurgije in materialov
    Among various parameters that influence the properties of the composite, the bond between the cementitious matrix and the fibres is the most important one. This paper investigates the influence of ... the air entraining agent on the improvement of the bond strength between bundled carbon filaments and cementitious mortars. The application of the air entraining agent caused the formation of air bubbles inside the mortar matrix and herewith induced inner compressive pressure on the fibres. Air bubbles formed in the vicinity of the fibre tow were found to provide mechanical anchoring of the fibres, leading to a significant increase in interfacial friction. An overall microstructural analysis and the fibre-bundle pull-out tests were caried out to confirm the effectiveness of the air entraining agent to improve the bond strength. Based on the resulting load-displacement curves, air entraining agent was found to be very effective in improving the bond strength and toughness of the composite.
