Formulation of Mix Design Procedure for Slag Cement

2018-9-28  The workability of the slag cement concrete increases due to increased paste cohesiveness, glassy structure of slag cement and low initial water absorption. Slag cement mixtures can achieve required strength at lower cementitious levels while maintaining good workability. Consolidation of slag cement concrete is generally easier than portland cement concrete. With constant water-cement ratios, slag cement

METALLOTHERMIC PRODUCTION OF CEMENT EXTENDER

2018-1-20  Ground granulated blast furnace slags (GGBFS), fly ash and silica fumes are currently used as cement extenders and major work has been done in improving these cement extender properties3-5. The objective of the pilot plant test work was to develop a process to produce a cement extender from high carbon ferromanganese slags. The slags contained an undesirably high amount of MnO with potential adverse effects on the cement properties. The intention of the test work was therefore to produce cement extender product from ferromanganese slag
