Ladle Furnace Slag in Construction

Abstract

Ladle furnace reducing slag is a common byproduct in steelmaking of carbon and low alloy steels. After air cooling and weathering over several days, this material is completely ground into fine white particles. Physical, chemical, and crystalline characterizations were performed in order to verify possibilities for its direct application as a construction material. Two ways are proposed for the immediate use of ladle furnace slag: masonry mortars and paving mixes for rural roads with low levels of traffic.
