Abstract Scope |
This paper deals with the development of new fire-resistant inorganic polymers based on recycled construction and demolition ceramic wastes, through the geopolymerization technology that achieves drastic reduction of energy demand and CO2 emissions compared to technologies currently used for commercial fire-resistant materials. Developed materials were tested at elevated temperatures and their structural transformations and mechanical and physical properties were investigated. According to the results, new materials appeared only negligible surface cracks after heating up to 1050 oC, without phenomena of apparent deformation or creeping. Their microstructural analysis revealed transformations of initial mineralogical phases to minerals with melting points higher than 1100 oC. After materials thermal testing, their residual compressive strength was ranged from 20 to 35 MPa and their mass loss in between 4 and 10%. Based on the findings of this study, the developed materials are promising to be applied for the passive fire protection of buildings and constructions. |
