dc.description.abstract | The aim of this study is to compare the mechanical and physical properties of different
geopolymer mortars made with granulated blast furnace slag as a geopolymer source material, NaOH
(8 M) as the activating solution, and three different types of fine aggregates (air-cooled blast furnace
slag, biomass bottom ashes, and silica sand). The samples were made with an aggregate/geopolymer
ratio of 3/1, and physical (density and mercury intrusion porosimetry), mechanical (compressive
and flexural strength), and acid attack resistance were determined. When air-cooled blast furnace
slag is used, the mechanical and acid attack properties are improved compared with silica sand and
biomass bottom ashes because of the existence of amorphous phases in this slag, which increase
the geopolymer reaction rate despite the particle size being higher than other aggregates. It can
be highlighted that the use of ACBFS as a fine aggregate in geopolymer mortars produces better
properties than in cement Portland mortar. | es |
