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 400oC temperature. The results show remarkable properties for some composites with respect to strength and durability
