A comprehensive review of destructive testing techniques to understand concrete behavior is presented in this work. The main objective of this article is to summarize the literature from the last three decades related to the following topics: 1) the size effect in plain and reinforced concrete, 2) the crack estimation and propagation in concrete under various loading conditions, 3) the determination of material properties of concrete using triaxial testing techniques, 4) the behavior of concrete under creep and early age shrinkage which eventually affect the properties of concrete and lastly 5) the strain rate effect in concrete using various experimental techniques such as Split Hopkinson pressure bar, impact loading, drop hammer and the literature related to cyclic loading on concrete. The scope of the presented work is limited to destructive testing related to the topics defined above. To completely understand the behavior of material, at least three aspects must be required: the material’s theoretical basics, experimental validation, and numerical implementation. The authors presented the review articles related to theoretical basics and numerical implementation in parts I and II of this article. The presented work is part III, which is related to experimental work. In the upcoming section, the research related to specific topics is presented, and a summary is provided at the end of each section. Finally, the future works and the research directions are shown in the conclusion section.

“…These structures were bombed and subjected to different kinds of dynamic loads, which are still going on. Another reasons are; use of unstandardized and low-quality construction material, equipment, practices, overloading, aging, and corrosion, which significantly weakens even new structures and requires maintenance (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) . Considering that building new structures in totality is costly and entirely out of Afghanistan's budget (and other third-world countries), a cost-effective strengthening method should be introduced.…”

Background/Objectives: FRP (Fiber Reinforced Polymer) has a wide range of application areas within the construction industry and is used in various forms and shapes, primarily for maintenance purposes. Using FRP has numerous advantages and disadvantages driven by several factors, including the country where it is used. The present paper focuses on the feasibility of using FRP in Afghanistan, considering load carrying capacity, cost, time efficiency, and environmental concerns as the main parameters. Method: In this numerical study, RC-jacketing and FRP-wrapping methods were evaluated for strengthening/repairing RC columns, and a comparison of the two methods was carried out to understand which approach better meets the maintenance needs in Afghanistan. Findings: As a result, the RC-jacketing method was more efficient in terms of cost and strength, while the FRPwrapping method proved its efficiency in terms of time and lower emission of CO 2. Moreover, the RC-jacketing method was found to be more suitable and aligned with the country's current architecture. Overall, as the cost is the leading parameter in a developing country like Afghanistan, RC-jacketing was more suitable for conducting the maintenance work. Additionally, the authors also recommended using the FRP-wrapping method in some particular circumstances where the RC-jacketing method was believed to be less efficient.
