XRD pattern of unblended and blended cement with GGBS (40 %). The XRD spectra of blended cement with 40 % replacement of GGBS ( Fig. 5 B, D & F), the peak of portlandite, Calcite & C-S-H, C 3 S and C 2 S are lower after an age of 3, 7 & 28 days in comparison to unblended cement due to dilution effect [ 37 ].

furnace slag (GGBS). In this study natural dolomite, as a source of MgO and CaO, was calcined at 800°C (D800) and 1000°C (D1000) under air. The activation of GGBS with the calcined dolomites was investigated using compressive tests, pH measurement of pore solutions, powder X-ray diffraction (XRD) and thermogravimetric analysis (TGA).

Furnace Slag (GGBS) is used as replacement to cement by weight. The GGBS is used as partial replacement for cement in the concrete mix with particles in the range of 125-250μm, 90- 125μm, 45-90μm, 20-45μm and <20μm. The dosage of GGBS is varied from 10% to 40% at an increment of 10% to evaluate the compressive strength of concrete

concrete. Ground granulated blast furnace slag (GGBS) was used at 10%, 20% and 30% cement replacement levels with the aim of reducing the cement consumption in concrete and the effect of the GGBS on the workability, compressive and flexural strength was investigated. The PQC (Pavement Quality Concrete) containing GGBS was also found to have 20-30%

GGBS Vertical Roller Mill

Introduction of GGBS vertical roller mill. GGBS vertical roller mill is the equipment to grind Ground Granulated Blast furnace Slag (GGBS) into small particles.GGBS (fineness:4200-4500cm2/g) produced by vertical roller mills are being used to substitute clinker in conventional cement manufacturing, for which the percentage of GGBS usage is typically at 10-15% and 20-25% respectively.

Consumption patterns are changing with younger generations. People born between 1981 and 1996 are radically changing the patterns of consumption established by their predecessors, in ways that are adversely affecting some industries and favouring companies which take advantage of the increasing spending power of younger consumers.
