Experimental investigation and prediction on the effects of glass and bamboo fibers as key mixture parameters in reinforced concretes using support vector regression.

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. [ABSTRACT FROM AUTHOR]
