Abstract:
This research investigates a novel combination of glass fibers, carbon fibers, and Polycarboxylate ether to enhance concrete's mechanical properties. The unique mix design, not previously explored in existing literature, aims to improve strength, durability, and sustainability in construction. The research involved casting concrete specimens incorporating varying proportions of hybrid combinations of glass fibers, carbon fibers, and Polycarboxylate ether as admixtures. Hybrid fiber Reinforced concrete (HFRC), Glass fiber reinforced concrete (GFRC) and Carbon fiber reinforced concrete (CFRC). Fiber combinations A: 0 % GF; B: 1.5 % GF + 0.5 % CF; C: 1 % GF + 1 % CF; D: 0.5 % GF + 1.5 % CF; E: 2 % CF. The PCE-based superplasticizer, used at 0.8 % in all combinations by the weight of cement. combination of glass and carbon fibers at a constant 2 % total fibers. Comprehensive tests were conducted on water absorption (cube), compressive strength (cube), split tensile (cylinder) and flexural behavior (beam) to evaluate performance enhancements over conventional concrete across 7th, 14th, and 28th days. Compressive strength 35.33 MPa, Flexural strength test 9.1 MPa, split tensile 5.60 MPa, and water absorption 6.31 at 28 days, Mix C achieved as compared with different ratios in M25 grade concrete.
