  • Durability of concrete made with manganese slag as ...

    This paper discusses mineral composition and pore microstructure characteristics of watercooled manganese slag and its effects on durability of concrete. The Mn slag has an alveolate pore structure, and the ground Mn slag is characterized by multiangular shape which consists of α′C2S, C3MS2, CaO·MnO·2SiO2 and C2AS. Experimental results show that the Mn slag has potential hydraulic ...
