Abstract

Basic oxygen furnace (BOF) slag is characterized by high hardness, low abrasion, and high roughness. It is suitable as graded aggregate for engineering applications. However, the conversion process generated a great amount of unreacted free CaO, resulting in expansion and thus making the slag inconvenient for use in engineering applications. Accelerated carbonation of BOF slag is equivalent to natural weathering. Moreover, it can effectively shorten the weathering time. This study found that accelerated carbonation not only reduce expansion behaviors but also strengthen physical and mechanical properties. According to test results, the abrasion resistant, soundness, California bearing ratio, shear strength, and compressive strength have increased after carbonation.
