...-dispersibility of underwater non-dispersible concrete with silica fume alone is the best, while that of underwater non-dispersible concrete with fly ash and mineral powder alone is the worst, and becomes worse with the increase of fly ash and mineral powder. The underwater non-dispersible concrete mixed with fly...

... the compressive strength of green concrete are still lacking. Design/methodology/approach To estimate the compressive strength of plain concrete, fly ash concrete, silica fume concrete and concrete with silica fume and fly ash, four predictive GEP models are developed. The GEP models are developed using...

... study was conducted to assess the acid resistance of fly ash-based geopolymer cement with nano-silica additive at a concentration of 0 and 1 wt.% to understand its effect on the strength and microstructural development. Geopolymer cement of Class C fly ash and API Class G cement were used. The alkaline...

...Syahrir Ridha; Afif Izwan Abd Hamid; Che Ku Afiza Hanim Che Ku Mazuan Purpose The purpose of this paper is to investigate the mechanical properties changing of geopolymer cement under different brine salinity. Design/methodology/approach Geopolymer Cement of Class F Fly Ash and Class G Cement...
