Abstract: A large quantity of filler is needed in the production of self-compacting concrete. Fillers can be made, but there is an abundance of by-products available from different industries. The use of by-products, from mineral and metallurgical industries, as filler in concrete requires a thoroughly characterisation of the materials. Material characteristics, such as the particle size distribution, particle shape, surface texture and the nature of the material influence the properties of fresh concrete mixtures more than they affect the hardened concrete. By-products/filler materials in the form of dust or sludge were collected from the metallurgical industry in Sweden. The materials were evaluated with different methods: the particle size distribution, surface area, particle shape and water demand (ßp) were determined and evaluated. In order to facilitate the use of by-products as fillers, a method of characterising changes in particle size distributions, PaRMAC was studied. The study shows that fine-grained materials from the metallurgical industries can be characterised, systemised and optimised in order to be used as fillers.
