Abstract

The  current  research  aims  to  investigate  alkali-activated  fly  ash  (AAFA)  concrete/mortar  modified  with
granulated ground blast-furnace slag (slag). FA was partially replaced with slag at levels of 0, 5, 10 and 15%, by
weight. The workability and mechanical properties of alkali-activated concretes were studied. Drying shrinkages of
alkali-activated mortars were investigated. All results of alkali-activated FA/slag concretes/mortars were compared to
control  concretes/mortars  based  on  plain AAFA.  The  results  indicated  that  the  workability  decreased  as  the  slag
content increased. Mechanical strengths and drying shrinkages increased with increasing slag content
