Engineering characteristics of ultra-high performance basalt fiber concrete incorporating geranium plant waste

This study investigates the sustainability aspects of Ultra-High Performance Basalt Fiber Concrete (UHPBFC) by using Geranium plant (GP) waste burned for 3 h at 300-900 degrees C at interval of 200 degrees C. The UHPBFC was used to partly replaced ordinary Portland cement (OPC) such that UHPBFC/ (UHPBFS+OPC) varied as 0.1-0.5 at interval of 0.1. Waste glass sheet powder and basalt fiber were incorporated as alternative fine aggregate and fiber reinforcement, respectively to improve mechanical, microstructure, transport and thermal performance of the concrete. Scanning Elec-tron Microscopy (SEM), Energy Dispersive Test (EDEX), and X-ray Diffraction Analysis (XRD) were conducted for product characteristics and microstructural analysis. The results showed a significant increase in mechanical properties for all mixes, and the optimum mixes are obtained at 50%, 40%, 40%, and 20% for mixes containing (GP) waste bumed at 300 degrees C, 500 degrees C, 700 degrees C, and 900 degrees C, respectively. In addition, the optimum results are obtained at 40% replacement burned at 700 degrees C with an increment increase of 14.5%, 17.6% and 30% for compressive, split tensile and flexural strengths, respectively. High sorptivity and fire resistances were obtained with 40% loss of strength at 900 degrees C with concomitant dense microstructure at h higher Ca/Si rado.
