Development of Metakaolin and Flyash Based Geopolymer Concrete at Ambient Temperature Curing,aded gravel with a maximum size of 12.5 mm and fine aggregates was M sand. From the present study geopolymer concrete of compressive strength 32.21 N/mm. was developed. The optimized mix was obtained with the activator to binder ratio 0.9 as well as 60:40 proportion of metakaolin and fly ash.使坚硬 发表于 2025-3-27 11:44:36
