Abstract

The research evaluates the thermal degradation effects of high temperatures on Geo Polymer Concrete Composite (GPCC) by examining alccofine concrete, concrete made with alccofine and porcelain waste aggregates. Knowing how GPCC behaves under high temperatures proves essential for protecting buildings during fires as well as industrial applications. Each mix design received composite concrete samples that underwent increased heating conditions from 100°C to 700°C at 200°C intervals. Post-heating, various parameters were analyzed, including weight loss, compressive strength reduction, and visual assessment of surface cracking and spalling. The results revealed distinct degradation patterns among the different concrete types. Nominal concrete exhibited significant strength loss and increased cracking at higher temperatures. GPCC demonstrated improved thermal stability compared to the nominal mix, showing less weight loss and strength reduction, likely due to the pozzolanic reaction of alccofine enhancing the microstructure. The combined addition of alccofine and porcelain waste aggregate GPCC further enhanced the thermal performance, exhibiting the least degradation among the three mixes. This suggests that the combined effect of alccofine and porcelain composite creates a denser and more durable microstructure, leading to better resistance against thermal damage. The study highlights the beneficial role of alccofine and the synergistic effect of alccofine and porcelain in improving the high-temperature performance of concrete, along with the promising thermal resistance exhibited by Geo Polymer Concrete Composite (GPCC), providing valuable insights for designing more fire-resistant composite concrete structures.

Keywords: Alccofine (AL), Compressive strength, elevated temperature, porcelain waste aggregate (PWA), geo polymer concrete composites (GPCC).
