Özet
The potential for enhancing the durability performance of AR-glass - cement composites by means of incorporation of nano-particles in between the filaments in the yarn was studied. The paper presents the results of bond studies to characterize the nature of pull-out and the potential of preservation of the telescopic mode of failure. The yarn-cement matrix bond was found to decline upon aging and relations between this decline and reduction in the tensile strength of the composite could be established. The incorporation of nano-particles into the yarn by impregnation with a slurry containing these nano-particles could provide an effective means for a drastic improvement in the aging performance of AR-glass textile reinforced composites. Complete preservation upon aging of the pull-out characteristics could be obtained only when inducing an effect which is in addition to the physical presence of the nano-particles between the filaments.
