چکیده
|
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.
