with 60% of GGBS to give sufficient strength for practical applications. Low- calcium fly ash (LCFA)- and ground granulated blast furnace slag (GGBS)-based geopolymer concretes are eco- friendly novel ...
to create different solid phases, which include calcium -aluminate-silicate-hydrate, which primarily impacts the strength , microstructural and durability properties [13–15]. Ultra- high performance geopolymer ...
-based geopolymers lead to complications such as reduced workability , high shrinkage, fast setting time [32], and loss of strength properties during carbonation. Mixing slag and silica fume seem very ...
tensile strength of concrete. Ferdosian et al. [26] used response surface methodology to study the effects of silica fume, ultra-fine fly ash and sand as three main constituents on the workability ...
and fly ash were activated with a mixture of powdered sodium hydroxide, silicate, and carbonate by the addition of sea water: accelerated setting, similar strength development as with tap water, and only ...
