Concrete, a vital material in construction, is facing challenges in enhancing its strength and durability. Researchers are exploring innovative approaches, such as using Fibre Reinforced Polymer (FRP) composites, to improve these properties. Structural flaws are often found during evaluations of existing buildings, especially older ones that may benefit from retrofitting. In this study, Manufactured sand was tested as a replacement for fine aggregate in concrete mixes to strengthen the mixes. The study utilized response surface methodology to predict the strength properties of sustainable Concrete mixes based on compressive strength. The flexure of reinforced concrete beams was evaluated using chopped strand mat (CSM) and glass-fiber reinforced plastic (GFRP) laminates. The study tested five RC beams using a 4-point bending configuration, with one beam serving as the control and the other four strengthened with FRP laminates. The results showed successful improvement in load-bearing capacity with GFRP + CSM laminates. However, thicker FRP sheets were not recommended as they can impact flexural strength. The GFRP + CSM enhanced beam achieved a 107% increase in ultimate load compared to the non-strengthened beams, according to experimental results. The strengthened beam had a greater rise load-carrying capability of 115 kN than the unstrengthen beam.

This article presents a concise overview of modern achievements and existing knowledge gaps in the area of biodegradable magnesium alloys. Hundreds of Mg-based alloys have been proposed as candidates for temporary implants, and this number tends to increase day by day. Therefore, while reviewing common aspects of research in this field, we confine ourselves primarily to the popular Mg-Zn-Ca system, taken as a representative example. Over the last decades, research activities in this area have grown enormously and have produced many exciting results. Aiming at highlighting the areas where research efforts are still scarce, we review the state-of-the-art processing techniques and summarize the functional properties attained via a wide variety of processing routes devised towards achieving a desired properties profile, including the mechanical response in terms of strength, ductility, and fatigue resistance paired with biocompatibility and bio-corrosion resistance or controlled degradability. We pay keen attention to a summary of corrosion properties and mechano-chemical interactions between an aggressive environment and loaded Mg-based structures, resulting in stress corrosion cracking and premature corrosion fatigue failures. The polemic issues and challenges practitioners face in their laboratory research are identified and discussed.

“…Severe plastic deformation (SPD) is an effective method to refine grain and improve the mechanical properties of materials. Equal Channel Angular Pressing (ECAP) [1-3], High Pressure Torsion (HPT) [4,5], Cyclic Extrusion Compression (CEC) [6], Accumulative Roll Bonding (ARB) [7], Multi-Directional Forging (MDF) [8] and so on are all existing SPD technologies. The ultrafine grain structure produced by SPD process facilitates the excellent performance.…”

In this work, the microstructure evolution and mechanical properties of 6201 aluminum alloy during multidirectional forging (MDF) and solution-aging were systematically studied. In the MDF process, the deformation of 6201 aluminum alloy was not uniform, and the increase of forging passes can effectively improve the inhomogeneity. With the increase of forging passes, the alloy changed from dynamic recovery to dynamic recrystallization, the grains in the center were refined obviously, and the anisotropy of microstructure was eliminated. After 9 passes of MDF followed by the solution-aging, the re-dissolution and re-precipitation behavior of the second phases significantly improved the mechanical properties of the alloy. The tensile strength, yield strength, elongation and conductivity of the alloy were 257 MPa, 139 MPa, 16.1%, 51.6% IACS, respectively, 55.8%, 73.8%, 3.4% and 10.5% higher than that of the as-cast alloy. At the same time, the average grain size of the alloy was decreased to 133 μm, 50.9% lower than that of the initial one.
