Rehabilitation of reinforced concrete beams subjected to torsional load using ferrocement
2023, Case Studies in Construction MaterialsImpact of tension stiffening on the tensile and flexural behavior of ECC ferrocement
2022, Construction and Building MaterialsCitation Excerpt :The experimental results showed that the repaired RC columns effectively regained their axial load capacity and stiffness and exhibited a ductile failure mode. In addition, polymer modified ferrocement has been developed for retrofitting RC beams and beam-column joints [18–21]. The advantageous mechanical properties of ferrocement have been popularized throughout the world and have motivated engineers to develop the structural components with desired configurations that are generally not possible with other construction materials [1].
Finite element model for the steel-polymer composite floor filled with phase-change amorphous polymers at elevated temperatures
2022, Construction and Building MaterialsCitation Excerpt :In addition, various concretes containing polymers, such as polyurethane (PU), polystyrene, polypropylene (PP), polyethylene, and polyvinyl, were also investigated to be used for repairing and reinforcing structural members and consider environmental issues [3-16]. Polymers are also used in the construction industry to reinforce and repair materials for main structural members, such as reinforcing polymer bars [17-19] and surface-mounted repairs [20]. In addition, fiber-reinforced polymer (FRP) [21,22], and PP straps [23] strengthen the structural performance of members.
The use of Wire Mesh-Polyurethane Cement (WM-PUC) composite to strengthen RC T-beams under flexure
2018, Journal of Building EngineeringCitation Excerpt :For the ferrocement-strengthened beams, a bonding aid was necessary to prevent the separation of the ferrocement laminates. Previous studies have shown that all beams without a bonding aid exhibit local debonding at the concrete/ferrocement laminate interface [13,14,27–29]. Thus, a bonding aid was used in all of the ferrocement-strengthened beams.
Investigation of ferrocement channels using experimental and finite element analysis
2015, Engineering Science and Technology, an International JournalCitation Excerpt :Other experimental studies have also suggested the applicability of polymer fibers instead of meshes in ferrocement. Moreover, ferrocement slabs are used as secondary roof structures to insulate against heat [31], in the manufacture of beams [32–36], and in building components such as doors [37] and drywalls [38]. The mechanical behavior of ferrocement elements such as beams, slabs, and columns has been examined under applied loads up to failure by experimental models such as Hago et al. [12] and Ibrahim [39] who studied experimentally the ultimate capacity of simply supported slab panels and ferrocement slabs.
Flexural behavior and crack-damage mitigation of plain concrete beam with a strain-hardening cement composite (SHCC) layer at tensile region
2013, Composites Part B: EngineeringCitation Excerpt :These have ranged from polymer modifiers for Portland cement-based products to pure polymers such as epoxy resins, polyesters and some polyurethane based systems. Other non-Portland cement-based materials, such as high alumina cements and magnesium phosphate-based repair products have also found application [2]. In recent years, rapid advances have been made in the development of strain-hardening cement composites (SHCCs) which is micromechanically designed cement composite and exhibits pseudo tensile strain-hardening behavior accompanied by multiple cracking while using a moderate amount of fiber, typically less than 2% in term of fiber volume fraction.
