Special Issue Information

Dear Colleagues,

Environmental awareness is gaining impetus among the population, and this is also reflected in the management of deteriorated structures. Older structures in all countries should be managed properly because they are the symbol of culture. Structural deterioration not only causes instability but also affects its real-time usage. Novel structural rehabilitation measures have been invented across the globe, but the processes have not yet been disseminated properly. Further, the environmental impacts of repairing materials have not been studied properly, and it is the need of the hour to understand their real impact. Obviously, the environmental impact of repairing materials can extend far beyond the construction standards of any nation. Hence, retrofitting a structure with ecofriendly materials will lead to more productivity and reduced spending. Further, while ecofriendly materials may not generate as much attention as generic projects, their influence is anticipated to be farther-reaching in a shorter span of time and will be of great importance in terms of public opinion. This Special Issue focuses on promoting and disseminating materials, tools, and techniques related to the repair and rehabilitation of older structures and building components in an ecofriendly manner. Topics to be covered include:

  • Novel repair methods for deteriorated structures;
  • Ecofriendly retrofitting methods;
  • Software-based analysis for retrofitting;
  • Low-density and low-weight materials for retrofitting;
  • Retrofitting for older structures;
  • Supplementary cementitious materials and their applications ;
  • High-strength materials for novel retrofitting;
  • Environmental impact of repairing materials;
  • Geomaterial innovation for repair and rehabilitation.

This research was conducted to evaluate the influence of waste granite powder (WGP) and polypropylene (PP) fibers on the performance of M35-grade pavement quality concrete (PQC). WGP was mixed in PQC as replacement for cement and was varied from 0% to 25%. The pozzolanic concert of WGP was examined by the strength activity index. The performance of PP fibers in PQC was assessed after the addition of fibers from 0.25% to 1.25% by volume of concrete. The mechanical properties of PQC were evaluated including the compressive strength, flexural strength, and various durability related properties such as the acid attack, absorption test, sorptivity test, and chloride penetration depth test. The results showed that PQC blended with WGP enhanced the strength slightly up to the replacement level of 15%. The addition of PP fibers rooted the reduction of the slump value; however, it improved the mechanical properties up to the presence of 0.5% PP fibers in PQC. The relationship between the compressive strength and flexural strength of WGP blended with PP fiber-reinforced PQC was established. Full article

In recent decades, corrosion in steel reinforcement has been one of the fundamental risks in steel-reinforced concrete (RC) structures. Geosynthetics can be an alternative approach to solve corrosion problems. The current experimental research work investigates the structural performance of geogrid-reinforced concrete (GRC) elements. Initially, five different geotextiles and biaxial geogrid materials were selected and embedded in the concrete specimens separately to study their mechanical properties. The results of the testing showed that the geogrid embedded specimen behaved more mechanically than the conventional concrete (CC) specimens due to increased bonding characteristics. The limiting moment and load-carrying capacities of the RC and GRC beams were determined with reference to limit state design principles. In order to compare the structural performance of the beams, two RC beams and two GRC beams with the size of 150 mm × 300 mm × 2100 mm were cast. The structural performances in terms of the load-carrying capacity, energy absorption, stiffness degradation, and ductility were examined. The results of the tests indicated that even though the load-carrying capacity of the GRC beams was slightly lower, they demonstrated enhanced performance by 42%, 40%, and 68% higher in the energy absorption, stiffness degradation, and ductility, respectively, than those of the RC beams on average. The augmented inelastic performance and better bonding properties of the GRC beams aid in noticeable structural performance. Full article
