Fine particulate metallurgical by‐products' influence on cement hydration and strength development: an initial study

Abstract

By‐products, such as dusts and sludges from metallurgical processes usually have a very fine particle size distribution and may be used, directly from the process of their origin, as a substitute for natural filler in concrete. To be able to promote the use of by‐products as fillers in concrete their effect on concrete properties has to be examined. This investigation has been made in order to gain knowledge of how fine particulate by‐products that contain metal oxides influence the cement hydration and concrete properties, such as strength development.
