When slag cement is mixed with water, however, the initial hydration is much slower than portland cement mixed with water; therefore, portland cement or salts of alkali metals, principally sodium and potassium or lime, are used to increase the reaction rate of slag cement (ACI 233R). The ASTM C989 slag-activity index is often used as a basic ...

PSC is manufactured by intergrinding Portland cement clinker, gypsum and granulated slag from steel plants. Due to contributions of slag in concrete durability and other environmental features, popularity of slag cement is increasing day by day.

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 …

Slag Cement is a promising type of cement due to its property of having sulfate and chloride resistance. It can be used in marine environments because of this. Slag Cement also has low heat of hydration compared to Portland Cement so it can be used in massive concrete structures.

Slag cement helps in two ways: 1) reduced permeability reduces the ingress of deleterious sulfates into the concrete and 2) slag cement does not contain tricalcium aluminate, and thus lowers the total amount available for reaction. The use of slag cement with a Type I portland cement can provide equivalence to a Type II (moderate sulfate ...
