Strength and stability characteristics of GGBS and red mud based geopolymer concrete incorporated with hybrid fibres

摘要

Ordinary Portland Cement (OPC) production produces substantial CO_2 emission. Geopolymer Concrete (GPC) will be of considerable cure to Global Warming related with construction industry since GPC replaces OPC completely or about 80 % with industrial waste products. In this study GPC was made up of Ground Granulated Blast furnace Slag (GGBS) and Red Mud (RM) incorporating hybrid fibres in various ratios. Results show that, among all the mixes, one mix showed the best mechanical properties owing to the incorporation of hybrid fibres and reduction of Red Mud.
