Abstract:
Describes an experimental study of mix designs and characteristics of fresh and hardened superplasticized concrete containing high volumes of blast furnace slag. Results show that using superplasticized concrete in a mix design with a large amount of blast furnace slag allows a lower water content than that of the base concrete, a lower superplasticizer dosage to attain the same increase in slump, and a somewhat lower percentage of fine aggregate. Also, the compressive strength of the hardened concrete was as high as that of the nonsuperplasticized concrete.
