What is the Composition of BFS (Blast Furnace Slag)?

Granulated slag is quickly cooled by large amounts of water to produce a granule which is sand-like and is mainly ground into a cement generally known as Ground Granulated Blast Furnaces Slag (GGBFS), or Type S slag cement. It also can be mixed with Ordinary Portland Cement Clinker to make a combined Type 1 cement.

Three-dimensional computer modeling of slag cement ...

A newly developed version of a three-dimensional computer model for simulating the hydration and microstructure development of slag cement pastes is presented in this study. It is based on a 3-D computer model for Portland cement hydration (CEMHYD3D) which was originally developed at NIST, taken over in the authors' group and further developed.
