Abstract
This paper investigates the possibilities of the use of sodium hydroxide activated
blast furnace slag for preparation of filtration barriers. The motivation for this research is
searching for cheaper and more eco-friendly alternative to sintering, which is commonly used
for filtration membranes preparation. Such an alternative could be alkaline activation, which is
able to bind slag particles together. Low amount of activator, low water to slag (w/s) ratio
together with pressure compaction was used to obtain microstructure with preserved
continuous porosity. To confirm this presumption scanning electron microscopy (SEM) and
mercury intrusion porosimetry (MIP) analyses were carried out.
