The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Properties of alkali activated slag-fly ash blends with limestone addition (2015, result): “The previous studies also show that a higher slag content in the alkali activated slag–fly ash mixes results in decreased setting times [20,43].”
Effect of GGBFS on setting, workability and early strength properties of fly ash geopolymer concrete cured in ambient condition (2014, methodology): “It also supports the fact that the higher the slag content in the paste, the quicker is the rate of setting [23,39].”
Mechanical, thermal insulation, thermal resistance and acoustic absorption properties of geopolymer foam concrete (2015, background): “The much higher reaction heat release rate for fly ash -based geopolymer mixes containing higher CaO or slag contents has b een demonstrated [21, 25].”
Factors influencing the compressive strength of fly ash based geopolymers (2016, background): “Relatively few publications are available in the literature [19-23] and thus further 86 investigations are needed to provide a better insight into the properties and performance of such binary 87 systems.”
Effects of slag substitution on physical and mechanical properties of fly ash-based alkali activated binders (AABs) (2019, background): “These findings are in agreement with previous studies [3, 30, 51, 52].”
