Ground-granulated blast-furnace slag (GGBS) is a supplementary cementitious material used in concrete and is produced by drying & grinding of Granulated blast furnace slag into a fine powder. GGBS’s intrinsic properties contribute towards manufacturing sustainable concrete with higher compressive strength, reduced permeability & resistance to chloride and Sulphate

Ground Granulated Blast Furnace Slag (GGBFS) is a fine glassy granule which encompasses cementitious possessions. GGBFS is gained as a derivative in the removal of iron from its ore. The procedure of removal of iron is the blast furnace. The slag that is gained on the iron ore is then detached and cooled down gradually, which results in the creation of nonreactive

Title: 226.1R-87: Ground Granulated-Blast Furnace Slag as a Cementitious Constituent in Concrete Author(s): Publication: Technical Documents Volume: Issue: Appears on pages(s): 16 Keywords: Date: 1/1/1987 Abstract: Note: 226.1R-87 is No Longer Available. The use of iron blast-furnace slag as a constituent of concrete, either as an aggregate or as a cementing

Ground Granulated Blast Furnace Slag (GGBFS) Brief Description . GGBFS is formed when granulated blast furnace slag (GBFS) is further processed or ground using conventional cement clinker grinding technology.. Physical Description. On a casual examination, GGBFS can be off-white in appearance and could pass for a powder fineness typically between 380m 2 /kg

be partially replaced with ground granulated blast furnace slag (GGBS). In this research effect of partial replacement of cement with GGBS on strength development of concrete and cured under summer and winter curing environments is established. Three levels of cement substitution i.e., 30%, 40% and 50% have been selected. Early-age strength of GGBS concrete is lower
