Flexural Behaviour of Hybrid Fibre-Reinforced Ternary Blend Geopolymer Concrete Beams

Geopolymer concrete is one of the innovative eco-friendly materials that has gained attention many researchers in sustainable development construction industry. The primary objective this experimental investigation to study flexural behaviour ternary blend geopolymer (TGPC) with various proportions hybrid fibres. In study, 27 reinforced beams were cast a TGPC grade M55 and tested under monotonic loading conditions. specimens length 1200 mm, depth 150 width 100 mm. Crimped steel (metallic) fibres polypropylene (non-metallic) used form effect on flexure. volume fractions varied up 1% an increment 0.5%, from 0.1% 0.25% 0.05%. test results analysed based first crack load, ultimate load-deflection behaviour, energy absorption capacity, moment-curvature relationship, ductility compared without reveals best alternatives for conventional cement concrete. addition potentially improves properties great extent. showcased HTGPC exhibited better than other combinations considered study. Additionally, effort was made develop model estimate strength fibres, predicted values found satisfactorily results.
