Fire Resistance of Geopolymer Concretes

摘要

This project carried out fire testing of geopolymer concrete specimens and associated laboratory testing. This report focuses on the outcomes of the series of pilot-scale tests on geopolymer concrete panels, which were conducted on a single geopolymer concrete formulation. Geopolymer concrete is derived from coal fly ash and metallurgical slag, which are reacted together with an alkaline 'activating solution' (sodium silicate in this case), blended with fine and coarse aggregate (quartz sand and crushed granite in this case) to generate a product which is similar in mechanical properties and general appearance to Portland cement concrete.
