  author={Li Qin and Chen Chen and Lifeng Shen and Jianping Zhai},
This paper presents a study on F-fly ash based geopolymer mortars using CFBC bottom ash as fine aggregates. The alkali activators were sodium silicate, sodium hydroxide and potassium hydroxide solutions. The study included the impact of aggregates addition amount, alkali activator, aggregate type on compressive as well as of flexural strength. The original materials and reaction products were analysed by XRD, FT-IR and SEM/EDS and a leaching system was conducted to measure the reactivity of… CONTINUE READING
