20-08-2017· A composite mineral binder was prepared by mixing ground granulate blast furnace slag (GGBS) and steel slag (GGBS/steel slag ratios are 1 : 1 or 3 : 2 by mass). The application of a composite binder in a massive concrete structure under severe sulphate attack is discussed by determining the hydration heat, adiabatic temperature increase, compressive strength, elastic …
15-09-2020· Alkali-activated materials are low-environmental-impact binders that can be obtained from the alkaline activation of industrial wastes. In this study, converter steel slag as the major raw material and ground granulated blast furnace slag (GBFS) as the modified material were activated by water glass with a modulus of 1.5 and a Na2O dosage of 4%. The hydration process, microstructure and ...

Mercury intrusion porosimetry study was carried out on ordinary Portland cement (OPC) pastes with 10% to 40% mineral additives, such as steel-making slag, granulated blast furnace slag and fly ash.
Carbon steel slag and stainless steel slag for removal of types are identified as blast furnace slag and steel slag (ClaveauMallet et al 2013) Blast furnace slag is produced from the conversion of iron ore into pig iron, and steel slag is produced as the pig iron is purified into steel Based on the type of steel, steel slag can also be divided into carbon steel slag and stainless steel slag

18-06-2020· This paper proposes that Ca2+ in steel slag (SS) has a weak early hydration activity when SS and granulated blast-furnace slag (GBFS) are used as alkali-activated cementitious materials. Herein, alkaline activators and Ca(OH)2 are used as indicators of Ca2+ reaction in the SS and GBFS system. It is found that the 28-day compressive strength of the cementitious material with 2 wt% …
Granulated Blast furnace slag (GBS) is a light coloured 0/4mm glassy sand produced by the rapid quenching of molten blast furnace slag using large volumes of water. Production and Processing GBS or Granulate as it is sometimes known is produced by rapidly cooling molten Blast furnace slag with water as the slag is tapped from the furnace.
Ground granulated blast-furnace slag (GGBFS) has replaced cement as mineral admixture at the ratios of 0%, ... To apply these models, when stainless steel reinforcement is used, ...
Ground granulated blast furnace slag (GGBS) GGBS is primarily a binder used as an addition to cement which uses the latent hydraulic properties of GGBS to produce Portland blastfurnace cement (6-35% of GGBS) or blastfurnace cement (36-90% GGBS) produced by blending at the concrete mixer, or as a factory blend at the cement factory.
Granulated blast-furnace slag. Granulated blast-furnace slag is produced by using water to rapidly cool molten slag. This type of slag is sold as a raw material for cement in Japan and overseas. Inquiry.
Granulated blast-furnace slag (blast-furnace cement) Steel slag is used as raw material for blast furnace cement. Compared to mixed cement, blast-furnace cement offers the great advantages of increased durability (high resistance to seawater, reduction in alkali-aggregate reactivity, etc.) and enhanced long-term strength, along with lower CO2 off-gassing.
The BOF cycle generates four types of iron and steel slag: Granulated Blast furnace Slag – GBSF. Air-cooled blast furnace Slag – ABS. Basic Oxygen furnace Slag – BOS. Other secondary metallurgical slag (Slag Steelmaking - SMS) Most of the slag resulting from the integral cycle is generated during the production of pig iron and is ...
19-04-2021· This study used ground granulated blast-furnace slag (GGBFS) and stainless steel reduced slag (SSRS) to produce mortar as partial cement replacement. The physical properties (compressive strength, flexural strength, tensile strength, and ultrasonic pulse velocity [UPV]) and durability (resistivity, resistance to sulfate attack, and autoclave expansion) were tested.
Blast furnace slag is produced when iron ore and other technical additives are used to produce pig iron, and later steel. Depending on the type of cooling, this turns into crystalline air-cooled blast furnace slag or glassy ground granulated blast furnace slag. Steel slag is produced during the manufacturing of steel from pig iron, scrap steel ...
