Ground Granulated Blast Furnace Slag
1. Ground Granulated Blast Furnace Slag Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron o...
متن کاملEffect of Na3PO4 on the Hydration Process of Alkali-Activated Blast Furnace Slag
In recent years, the utilization of different non-traditional cements and composites has been increasing. Alkali-activated cementitious materials, especially those based on the alkali activation of blast furnace slag, have considerable potential for utilization in the building industry. However, alkali-slag cements exhibit very rapid setting times, which are too short in some circumstances, and...
متن کاملThe Study of Ion Adsorption by Amorphous Blast Furnace Slag
In this study, the blast furnace slag was used as absorbing bed and then, its ionic adsorption was studied. For this reason, various experimental parameters such as pH, contact time and the primary ion concentration were investigated. The remaining concentrations of ions such as; Mn2+ and Fe2+ in water were measured by atomic adsorption spectroscopy. The chemical and p...
متن کاملModeling Ecosystem Development on Blast-Furnace Slag Dumps in a Tropical Region
A deterministic mathematical model for ecosystem development on slag dumps has been formulated and based on five components of the ecosystem—soil total nitrogen, plant biomass, plant cover, soil moisture, litter, and soil fine particles. Nitrogen and soil moisture, which regulate vegetation development on the slag dumps, have been used as the driving parameters of the model. The numerical resul...
متن کاملEFFECTS OF SILICA MODULUS AND ALKALI CONCENTRATION ON ACTIVATION OF BLAST-FURNACE SLAG
Abstract: The use of alkali-activated cementitious materials especially over the past decades has significantly been increased. The goal of this research is to investigate the effects of silica modulus and alkali concentration on alkali-activation of blast-furnace slag. In this research, the most important physical characteristics of cementitious systems, i.e. the 28-day compressive strength...
