Abstract
In this research, 18 different synthesized geopolymer composites were prepared and
tested. These mixes were based on metakaolin, silica fume and slag as source materials
and different ratios of cement kiln dust, copper slag and fly ash. Compressive strength
and durability were measured for all mixes cured by different techniques. Compressive
strength were measured at 3, 7, 14, 28, and 90 days while durability was tested against
and exposure to sea water, nitric acid with 8% concentration and against fire at 400
o
C
temperature. The results show remarkable properties for some composites with respect
to strength and durability.
