Lightweight Flame-retardant Material Reinforced with Hevea Brasiliensis Ash Intumescent Agent

Abstract Flame retardant materials play an important role in many building construction components. The ability of components to resist fire is crucial the safety and well-being occupants. This research examines a lightweight flame-retardant material-Vermiculite (V) reinforced with renewable Hevea Brasiliensis Biomass Ash Intumescent Agent (HBAIA) different compositions. Four specimens vermiculite HBAIA (V/HBAIA) standard size 200 mm x 10 (W Lx H) were fabricated for investigations. All V/HBAIA assessed terms their density, fire-resistant, endurance smoke, char surface morphology, flexural toughness. Data disclosed V/HBAIA-2 composition 90% 10% obtained most prominent outcomes overall. attained lightest density 37.5 kg/m 3 weight 0.20 kg, lowest end temperature 122 °C after exposure one-hour 1000 fire. indicated best fire-resistant performance V/HBAIA-2. No structural deformation only mild smoke odor observed during examination. was able maximum loading force 67.4 N before 52.5 resistant, higher toughness value 1.47 MPa. Scanning electron microscopy revealed more uniform, denser, closely connected air cavities cell quality explained its superior as compared rest specimens.
