Abstract

This study investigated the possibility of developing self-compacting concrete (SCC) utilising silicomanganese fume (SMF), an industrial waste material. SCC was produced by replacing cement with 10, 20, 30, 40, 50, 60, 70, 80 and 90% SMF. First, an assessment of the fresh properties of 10 SCC mixtures was carried out, and then mixtures satisfying the fresh requirements were selected for further evaluation. Plastic shrinkage and setting time of the fresh SMF-SCC mixtures were measured, and thereafter the mechanical properties and drying shrinkage were evaluated. The incorporation of SMF increased the dosage of superplasticizer required for a certain flow, but it enhanced the filling ability and passing ability of SCC. In addition, the incorporation of SMF increased the plastic and drying shrinkage, as well as initial and final setting times. Although there was an improvement in mechanical properties of SCC mixtures containing 10 and 20% SMF, increasing the quantity of SMF beyond 20% negatively affected the mechanical properties. Furthermore, the use of SMF decreased the cost of SCC by 7–42% and the CO2 emission decreased by 10–68%.
