The use of CEM III/B blastfurnace slag cements and fly-ash in the concrete mix design are often recommended for improving the acid resistance and representing the actual best state of art in the construction of cooling towers of coal-fired power stations exposed to a high risk of sulfuric acid attack [13,14,15].

For blastfurnace cements (slag replacement >20%), the filler effect cannot compensate for the dilution effect caused by the large incorporation of slow reactive particles of slag [1]. Then, Wn ( Fig. 2 b and c) is less for both blastfurnace cements and all w/b used for pastes cured at 20 °C and consequently the compressive strength …

Ground granulated blastfurnace slag (GGBS) is a by-product of the steel industry. During the production of iron, a composite of iron-ore, coke, and limestone is fed into the blastfurnace, whereby iron-ore is reduced to iron and separated from the remaining slag. The slag is tapped-off and cooled rapidly to retain its cementitious …

AbstractThe influence of low curing temperatures (5, 10 and 15 ± 2 °C) on the strength and durability properties of ground granulated blastfurnace slag (GGBS) and ground granulated Corex slag (GGCS) concretes was studied. A standard curing temperature of 23 ± 2 °C) was also used for comparative purposes. Test specimens were …

Introduction. Metallurgical industry produces slag as by-products. Iron blast furnace slag is the major non-metallic product consisting of silicates and aluminosilicates of calcium. …

1. Introduction. Ground granulated blast-furnace slag (GGBS) is an industrial by-product of steel manufacturing, and is widely used as a supplementary cementitious material (SCM) in concrete production to partially replace ordinary Portland cement (OPC) [1].The use of GGBS as a SCM not only reduces the porosity of OPC …

11.2.2 Ground-granulated furnace slag. Ground granulated blast-furnace slag, GGBFS, is a by-product of iron in blast-furnace. It mainly consists of silicate and aluminosilicate of melted calcium that periodically needed to be removed from the blast furnace. Similar to fly ash, the chemical compositions of GGBFS depend on the row materials used ...

A general characterization of the early stage hydration behaviour of ground granulated blastfurnace slag/ordinary Portland cement blends reacting in the temperature range 20–60°C has been made by thermal and electron microscopic techniques. In the blends studied, both the silicate and aluminate associated reactions were accelerated by …

Dredging activities generate a huge amount of dredged clay slurry, and the treatment of it has been a challenge. Carbide sludge (CS)-activated ground-granulated blastfurnace slag (GGBS) can effectively stabilize clay slurry. However, in previous studies, the mechanical performance of CS–GGBS-treated slurry was only investigated …

Reactive magnesia (MgO)-activated ground granulated blastfurnace slag (GGBS), with fixed GGBS dosages but varying MgO/GGBS ratios, was used for stabilization of two soils and compared with brucite (Mg(OH)2)-activated GGBS and hydrated lime (Ca(OH)2)-activated GGBS. A range of tests, including unconfined compressive strength testing, X …
