“…Synthetic FRP jackets have also been reported to enhance the mechanical properties of CRAs [ 31 , 32 , 33 ]. Two concerns are identified with the use of synthetic FRP jackets: (1) the production of synthetic FRP jackets includes chemicals that can affect the skin [ 34 , 35 ], and (2) these jackets are expensive and may not justify their costs for low-budget strengthening projects [ 36 , 37 , 38 ]. This has urged researchers to move towards low-cost and sustainable replacements of the synthetic FRPs.…”

Given the excessive demolition of structures each year, the issues related to the generated structural waste are striking. Bricks being a major constituent in the construction industry, also hold a significant proportion of the construction waste generated annually. The reuse of this brick waste in new constructions is an optimal solution considering cost-effectiveness and sustainability. However, the problems related to the substandard peak stress and ultimate strain of concrete constructed with recycled brick aggregates (CRAs) limit its use in non-structural applications. The present study intends to improve the unsatisfactory mechanical characteristics of CRAs by utilizing low-cost glass fiber chopped strand mat (FCSM) sheets. The efficacy of FCSM sheets was assessed by wrapping them around CRA specimens constructed with different concrete strengths. A remarkable increase in the peak compressive stress and the ultimate strain of the CRA specimens were observed. For low, medium, and high strength CRAs, the ultimate strain improved by up to 320%, 308%, and 294%, respectively, as compared to the respective control specimens. Several existing analytical models were utilized to predict the peak compressive stress and ultimate strain of the CRAs strengthened using FCSM sheets. None of the considered models reproduced experimental results accurately. Therefore, equations were formulated using regression predicting the peak stress and ultimate strain of the CRAs confined with FCSM sheets. The predicted values were found to correlate well with the experimental values.

“…Fiber-reinforced polymer (FRP) composites have gained significant attention due to their distinctive characteristics such as high performance at low weight, corrosion resistance, ease of transportation and application, and tailorability (Balla et al, 2023;Liu et al, 2022;Saafi, 2000;Zhang et al, 2017). A considerable amount of literature has been published on the use of FRP in construction Page 2 of 23 Altunişik et al Int J Concr Struct Mater (2023) 17:55 applications and exhibits the performance of FRP under various loading conditions along with different structural materials (Abdullah & Bailey, 2018;Alotaibi et al, 2022;Ghazizadeh et al, 2018;Kim, 2019;Li & Harries, 2018;Lin et al, 2022;Louk Fanggi & Ozbakkaloglu, 2015;Muc et al, 2020;Noël, 2019;Sun et al, 2022;Wei et al, 2019). Properties such as the type of resin, fiber, and fiber placement are the main contributors to the performance of FRPs.…”

The past two decades have witnessed rapid advances in the use of fiber-reinforced polymer (FRP) composites in different engineering fields. Advantages such as high strength-to-weight ratio, corrosion resistance, and tailority have led to immense interest in the use of FRPs in wide spectrum repair and strengthening of structures. Despite their many advantages, FRPs are highly sensitive to high temperatures, which pose a major concern for fire potential structures such as buildings. Applying proper thermal insulation can enhance the fire performance of FRP and reduce the possible fire damage to the FRP strengthened element. This study set out to experimentally investigate the effectiveness of two insulation systems, “FIRECOAT” and “REALROCK” on fire performance of CFRP and GFRP strengthened concrete specimens. Various configurations and exposure durations were considered to evaluate the effectiveness of insulating materials. To perform the experiments, cylindrical concrete specimens were fabricated and strengthened using CFRP or GFRP. After insulating the specimens, they were exposed to a standard fire curve for two different durations of 30 and 60 min. The results indicate that less than 30 min of fire, both insulation systems can provide the required protection. During long exposure duration of 60 min, only REALROCK can provide the required thermal resistance for FRP-strengthened concrete. Within the tested materials, Fire Set 60 outperformed other insulating materials. It was observed that implementing Fire Set 60 in the innermost layer of thermal insulations has crucial importance in preventing the fire induced reductions in strength of FRP-strengthened concrete elements.
