摘要: Abstract The present work deals with elevated temperature properties of basalt microfibril filled geo-polymer composites when exposed to 200, 400 and 800 °C. microfibrils were obtained after 30 min dry pulverization fibrous wastes. Further, the added into geopolymer synthesized from calcined kaolin shale clay residues under 5, 10 15 wt% loading. prepared evaluated for physical properties, microstructural analysis compression strength before exposure temperatures. geopolymers was found higher than neat due their increased thermal resistance dense microstructures. composite 10 wt% maintained residual compressive strengths 23.13 16.08 MPa at 400 °C 800 °C, respectively thus recording a minimum loss 32 43%, respectively.
