Slag powder processed into cement

What is Slag Cement? (with pictures)

30/12/2020  Slag cement, often called ground granulated blast-furnace slag (GGBFS), is one of the most consistent cementitious materials used in concrete. It is actually a byproduct of iron production. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace.The molten slag

How Cement Is Made

Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.

Sulfate Attack - Slag Cement

The use of slag cement is also an extremely effective way of reducing the potential for sulfate attack 1. How does Slag Cement Mitigate Sulfate Attack? The use of slag cement reduces the likelihood of sulfate attack in three ways: Slag cement does not contain C 3 A, so its addition in concrete dilutes the total amount of C 3 A in the system.

Concrete Design Production - Portland Cement

Self-Consolidating concrete (SCC) is a high-performance concrete that can flow easily into tight and constricted spaces without segregating and without requiring vibration. The key to creating self-consolidating concrete (SCC), also referred to as self-compacting, self-leveling, or self-placing concrete, is a mixture that is fluid, but also, stable, to prevent segregation.

What are the effects of slag powder in mortar?

Since slag powder has a stronger effect of adsorbing chloride ions, it can effectively prevent chloride ions diffusing into it, improving the resistance to chloride ions. The resistance to sulfate attack of mortar depends on its resistance to penetration as well as the aluminate content and alkalinity in cement. In the slag powder mortar, the aluminate content and alkalinity are lower and it ...
