Blast Furnace Slag

Blast Furnace Slag

Blast furnace slag is a nonmetallic coproduct produced in the process. It consists primarily of silies, aluminosilies, and calciumaluminasilies. The molten slag, which absorbs much of the sulfur from the charge, comprises about 20 percent by mass of iron production.

A retarding effect of the slag on the Portland clinker hydration was observed, which became more pronounced for higher slag fineness. Finally, mortar compressive strength was tested at 2, 7 and 28 days and compared with the calorimetric results and with thermogravimetric analysis, used to determine the bound water content, at 28 days.

Manganese Slag

Manganese Slag

Manganese slag is a byproduct of ferromanganese alloy manufacturing. Two kinds of slag can be generated in the production of ferromanganese and ferromanganese–silicon alloys: aircooled slag also known as lumpy slag, and watercooled slag also known as granulated slag. 90 Approximately 900 kg of manganese slag is generated per tonne of ferromanganese alloy produced, 90 and the global ...

What is the effect of fineness of cement?

What is the effect of fineness of cement?

Increasing fineness causes an increased rate of hydration, high strength, and high heat generation. Bleeding can be reduced by increasing fineness. However, increased fineness can also lead to the requirement of more water for workability, resulting in a higher possibility of dry shrinkage.
