How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Mortar-based composites are an emerging technology for the repair and strengthening of reinforced concrete and masonry structures. In most cases, the effectiveness of the retrofitting work relies on the substrate-to-composite bond capacity but in some applications, connectors are also used to prevent debonding and improve the performance of the ret...
This paper aims at investigating the matrix-to-textile stress transfer in a fabric reinforced cementitious matrix FRCM system, not bonded to any substrate, under shear loads. To this end, direct shear tests are performed on a basalt FRCM specimen introduced into an innovative properly designed four-hinge frame loaded by a universal testing machine....
Steel reinforced grout is one of the most effective mortar-based composites for the strengthening of masonry structures. Nonetheless, the deterioration of steel cords, especially when embedded in lime-based matrices, may compromise the long-term effectiveness of the strengthening systems. The use of stainless-steel may overcome this drawback, but i...
Steel Reinforced Grout (SRG) is an effective, cost-efficient and versatile technology for strengthening existing structures. However, the high strength properties exhibited by steel textiles can rarely be fully exploited in design, due to the premature occurrence of bond failure and deterioration. Because of the small diameter of steel cords or wir...
Fabric reinforced cementitious matrix (FRCM) composites are widely used for retrofitting existing structures, especially in earthquake prone areas. After nearly two decades of scientific studies, experimental evidence proves their effectiveness for enhancing the ultimate strength and displacement capacity of masonry walls. There remains a need to d...
