INFLUENCE OF BLAST FURNACE SLAG CONTENT ON THE SULFATE DURABILITY OF THE PERLITE BASED GEOPOLYMER MORTARS

Session

Architecture and Spatial Planning

Description

In this study, the influence of blast furnace content on the magnesium sulfate resistance of the perlite geopolymer mortars was investigated. For the purpose, perlite was activated with 10M NaOH solution and blast furnace slag was replaced by perlite in three different proportions according to the CaO/SiO2 oxide ratio. The ultrasound pulse velocity, flexural strength (ffs) and compressive strength, water absorption, and magnesium sulfate durability of the geopolymer mortars were investigated. The test results indicated that the blast furnace slag improved the mechanical properties and the magnesium sulfate resistance of the perlite geopolymer mortars.
