The influence of MgO as a replacement of CaO seems depending on both the basicity and the MgO content of slag. Variations in the MgO content up to 8-10% may have little effect on strength development, but high content have an adverse effect. It also reported that MgO in amount up to 11% was quantitatively equivalent to CaO.

Keywords: Geopolymer cement, Natural Pozzolan, Granulated blast furnace Slag, Mechanical Properties, Microstructure A number of geopolymer cement mixes were designed and produced by alkali-activation of a pumice-type natural pozzolan. Effects of blast-furnace slag on basic engineering properties of the mixes were studied.
Cemented paste backfill (CPB) allows environmental friendly management of potentially hazardous tailings generated from milling of nonferrous metal sulphide ores by placing such tailings into the underground mined-out openings. The components of CPB are tailings, water, and binders. These components significantly affect the physicomechanical, workability, and geotechnical properties of CPB.
