High-temperature Resistance of Lateritic Soil-based Geopolymer Concrete in Comparison with Portland Cement
The production of Portland cement pollutes the environment and waste energy, which does not meet the requires of the eco-friendly development. This study aims to investigate the resistance of lateritic soil-based geopolymer concrete at elevated temperatures $(20 \sim 1000^{\circ}\mathrm{C}$) to expand the application range. This study reported both fresh properties (slump and porosity) as well as high temperature performance (physical appearance, compressive strength development, and mass loss) of geopolymer (GPC) or Portland cement concrete (PCC) with various mixtures. The experimental results revealed that the superplasticizer could improve the fresh properties of PCC, and the slump value and porosity reached 100mm and 11.57%, two types of GPC presented worse porosity of more than 18%. Besides, GPC presented acceptable strength/mass retention together with physical appearance after exposed to high-temperature compared to PCC, especially at temperatures of over 500°C.
