Effect of acidic environment on the bond behavior of TRM composites through sin...
Azimi, Nima; Oliveira, Daniel V.; Schollbach, Katrin; Lourenço, Paulo B.Textile Reinforced Mortars (TRM) for strengthening existing masonry structures are widely used these days as a sustainable solution. The system is comprised of textile fibers embedded in an inorganic matrix, typically cement or lime-based mortars, and is utilized over the surface of the substrate. Despite extensive research on the mechanical properties of these composite systems, there is still a lack of knowle...
Integrating experimental analysis and gradient boosting for the durability asse...
Taheri, Ali; Azimi, Nima; Oliveira, Daniel V.; Tinoco, Joaquim; Lourenço, Paulo B.This paper presents a comprehensive study of the mechanical properties of lime-based mortar in an acidic environment, employing both experimental analysis and machine learning to model techniques. Despite the extensive use of lime-based mortar in construction, particularly for the strengthening of structures as externally bonded materials, its behavior under acidic conditions remains poorly understood in the li...
Coated sisal/PET hybrid braided textiles interface behavior into cementitious m...
Kohan, Lais; Azimi, Nima; Aguiar Souza, Ivis; Fioroni, Carlos; Azevedo, Adriano G. S.; Freitas, Tais Oliveira Gonçalves; Peixoto, Joaquim Jorge GomesIntra-ply hybridization of two different braided yarns can enhance flexural and shear strength compared to conventional yarn properties. Hybrid braids offer the potential to reduce costs and boost industrial productivity. An impregnated textile with resin coating exhibits more cohesive behavior, ensuring stress distribution throughout the yarns and preventing a reduction in the composite’s ultimate tensile capa...
Effect of acidic environment exposure on mechanical properties of TRM composites
Azimi, Nima; Schollbach, Katrin; Oliveira, Daniel V.; Lourenço, Paulo B.With the increasing application of textile-reinforced mortars (TRMs) for the strengthening of existing masonry structures, knowing the long-term behavior of these composites is increasingly of great importance. In recent years, there has been a progressive research effort on the durability of TRM composites following different aging protocols, yet the durability of TRMs still necessitates comprehensive experime...
Tensile behavior of textile-reinforced mortar: influence of test setup and laye...
Azimi, Nima; Esfahani, Ali Dalalbashi; Oliveira, Daniel V.; Ghiassi, Bahman; Lourenço, Paulo B.Textile-reinforced mortar (TRM) systems are a popular solution for strengthening existing masonry structures these days. The vast application of these materials requires a thorough study of their properties and performance. The tensile behavior of TRMs has a significant role in their mechanical properties and requires a reliable setup to record their performance. Studies in the past focused on different grippin...
Tensile behavior of textile-reinforced mortar: influence of the number of layer...
Azimi, Nima; Oliveira, Daniel V.; Ghiassi, Bahman; Lourenço, Paulo B.In the last decade, textile-reinforced mortar (TRM) composites have been introduced as a sustainable solution for the strengthening of masonry structures. As an externally bonded reinforcement system, it consists of textile fibers embedded in an inorganic matrix (e.g., lime or cement mortar) applied to the substrate. Even though many studies have been focused on characterizing the mechanical behavior of TRM com...
