“…Glass fiber reinforced concrete is mainly utilized for the development of thin exterior buildings and architectural prefabricated cladding panels. The alkali resist‐water dispersed glass fiber 26 chopped strands are mixed with the concrete. Such materials can enhance the durability and strength of concrete structures.…”

Nowadays, reinforcement of fiber is necessary for concrete to enhance its quality with mechanical characteristics. The main objective of this work is to determine the mechanical properties of bamboo and glass fiber reinforced concrete. In concrete, E‐glass and bamboo fibers are mixed with three different proportions such as 25:75, 50:50, and 75:25. Cubical‐, beam‐, and cylindrical‐shaped concrete structures are developed for mechanical testing. After the curing period, the cubical structures are utilized for compressive strength testing, the cylindrical specimen for split tensile testing, and the beam‐shaped specimen for flexural strength testing. From the outcomes, 1% fiber substance (glass and bamboo fiber proportions of 75:25) provides better split tensile strength 4.13 N/mm2, compressive strength 42.08 N/mm2, and flexural strength 7.7 N/mm2. The comparative analysis of the proposed concrete composition with the conventional concrete mixture is also carried out. The experimental results are validated using support vector regression, and such predicted outcomes are closer to the experimented values. Furthermore, the ETABS platform is utilized for validating the proposed hybrid fiber reinforced concrete (HFRC) with single reinforcement‐like glass particles. In which, the testing properties like bending moment, shear force, and axial force are favorable for the HFRC.

“…Glass fibers are also used in geotextiles as a nonwoven reinforcing material for soil stabilization, because the spatial orientation is random and the resulting structures are flexible, while imparting stability and strength to the engineered soils [67,68]. Another application of glass fibers refers to reinforced concrete formulations used in civil engineering [69,70], when materials with extended service life, fire resistance and improved thermal and mechanical characteristics were obtained. Aramid fibers dominate the market of high-performance polymer materials.…”

Geotextiles, a group of high-performance materials, have grown during the last decades into needful auxiliaries when it comes to infrastructure, soil, construction, agriculture and environmental applications. Although geotextiles made of synthetic fibers (geosynthetics) are considered a modern achievement, the basic concept dates back to ancient times when textiles consisting of locally available natural fibers were employed to increase the stability of roads and soils. In recent decades, considering the growing interest in environmental protection and sustainable development based on using renewable resources and the recovery and recycling of waste of various origins, the use of natural fibers-based geotextiles is a viable alternative, despite their limited-life service owing to their biodegradability. In addition to this feature, their low cost, good mechanical properties and large-scale accessibility recommend them for geo-engineering applications, environmental sensitive applications in geotechnical engineering, such as land improvements and soil erosion control. This paper focuses on geotextiles as a versatile tool in environmental applications given their high theoretic and practical relevance as substantiated by recent literature reports. Natural and synthetic geotextiles are presented herein, as well as their features that recommend them for geo-engineering. Insights on the main types of applications of geotextiles are also included, along with a wide variety of materials employed to perform specific functions.

“…Ali et al prepared concrete cylindrical columns for them to be tested under compression with CFRP confinement. CFRP wrapping was done in three distinct ways: (A) on entire profile, (B) in the middle and at (C) upper and lower end although confinement ratio was held constant [12]. Results revealed that confinement is responsible for both increase in strength and ductility of samples.…”

Polymer concrete (PC) has acquired niche in construction industry due to superior mechanical properties, recyclability and adoption of variety of aggregates. This workpresents compressive behavior and properties of one such novel PC i.e. tin slag/polyester polymer concrete. Comparable siliceous content of tin slag was considered promising to provide better mechanical strength as in natural aggregates. Cylindrical short column specimens were fabricated to be tested under quasi-isostatic loading rate of 1 mm/min. Three different aggregate sizes in gap-graded configuration were tested to assess influence on mechanical properties. In addition, specimens were confined with GFRP and CFRP to determine and compare mechanical behavior with Portland Cement Concrete (PCC). Coarsest size (4+2 mm) aggregate offered the highest strength of 37.71 MPa for unconfined sample. This performance of coarsest size persisted in confined condition with compressive strength increment of 69.68 MPa (84.7%) and 98.36 MPa (160.8%) for one and two layers GFRP; 86 MPa (128.05%) and 125.07 MPa (231.66)% for one and two-layer CFRP, respectively. It was concluded that both increment in aggregate size and number of layers improved the compressive strength.
