✦ Synopsis

Methods for determining the codtent of blast furnace slag (BFS) in blended cements composed of BFS and OPC have been briefly reviewed. A variety of dissolution orocedures were investigated and the results compared critically.

Extractions with methanol-salicyclic and/or acetic acid show that these solvents attack the BFS but fail to dissolve certain components of the cement which have been identified by X-ray diffraction.

A recent method involving EDTA solvent extraction appeared more promising and additional work was undertaken to verify and improve it.

The method was used to determine BFS content of blended cements hydrated for periods up to 12 months.
