As known, to manufacture conventional concrete and/or mortar, portland cement should be used as a binding
constituent. Raw materials are supplied from natural sources to produce cement. In addition, high energy is required
during cement production. Moreover, high amounts of carbon dioxide are released into the atmosphere at a certain
temperature range when the cement is being produced. Therefore, geopolymers are alternative products to materials
having ordinary cement.
In this experimental work, nano silica and granulated blast furnace slag were used as powder materials. Influence
of curing regimes on the properties of the geopolymers was evaluated. Unit weight, water absorption, porosity and cap-
illary attraction were determined by conducting tests on specimens. Results showed that properties were influenced
negatively due to the presence of nanoparticles. Absorption, apparent porosity and capillarity decreased by increase in
fumed nanosilica. Additionally, curing regime is a significant factor especially for absorption characteristics.
