Abstract
A key concept of sustainability is the preservation of resources, thus adding life to existing concrete structures by means of durable strengthening and rehabilitation methods is a key objective. Composite materials, such as FRCM (Fabric-reinforced Cementitious Matrix), have proven to be a viable option for increasing durability of existing building stock. Experimental works show that the main failure mode of FRCM, applied to masonry or concrete substrates, is by debonding at the fabric/matrix interface. Mere, the idea is to use an epoxy coating and a layer of quartz sand in order to increase the adhesion of the fabric with the matrix. The effectiveness of coating treatments was studied by means of tensile tests, as indicated in AC434 Annex A. Tests were carried out on seven different types of fabric, with different levels of pre-impregnation and with or without quartz sand applied to the fabric surface. Experimental evidence shows a promising enhancement of the bond between fabric and matrix and, therefore, of the entire strengthening system even with the use of low percentages of resin, depending on the type of mortar.
