Absorption property of concrete is very much important in recent aggressive environmental conditions. The main components of blast furnace slag are CaO (30–50%), SiO 2 (28–38%), Al 2 O 3 (8–24%), and MgO (1–18%). In general, increasing the CaO content of the slag results in raised slag basicity and an increase

The formation process of blast furnace slag is mainly divided into three steps: primary slag, intermediate slag, and tapped slag. (1) Primary slag. It is formed along the top edge of cohesive zone and starts to drip when flowing to the lower edge of cohesive zone. The formation of primary slag includes solid-state reaction, softening, melting ...

The blast furnace slag ball mill is different from the conventional ball grinding mill in structure due to the coarse grain is less and the large plasticity of the iron and iron oxide components. Usually cement mill advocates more crushing and less grinding, but this is not suitable for blast furnace slag grinding. The blast furnace slag has a ...

Fly ash and Blast Furnace Slag for Cement Manufacturing GBFS is slag from the iron production in Basic Oxygen Furnaces. When this slag is actively cooled and ground, GBFS is produced, which can be utilised as a cement or concrete addition. GBFS is said to increase durability of concrete due to an increased setting time, which reduces
