ground granulated blast furnace slag - cement industry

Jan 30, 2020 · Cemfree uses 95% ground granulated blast furnace slag (GGBFS) and a 5% alkali activator, removing the need for cement. This gave CO2 emissions of 114kg/t, which the company says is 77% lower than conventional (OPC). Published in Global Cement News

what is slag cement or ground granulated blast-furnace

Granulated slag is the glassy, granular material formed when molten slag is rapidly chilled. Slag cement or GGBFS is granulated blast-furnace slag that has been finely ground and that is hydraulic cement. When slag cement is mixed with water, however, the initial hydration is much slower than portland cement mixed with water; therefore

ground granulated blast furnace slag - an overview

Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3 ), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the

ground granulated blast-furnace slag – jsw cement

Ground Granulated Blast-Furnace Slag. Slag is a by-product from steel plants, which is obtained from blast furnaces, during the separation of iron from iron ore. The process involves cooling of the slag through high-pressure water jets, this leads to formation of granular particles. The granulated slag is further processed by drying and then

what is slag cement

Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield

ground granulated blastfurnace slag - sharjah cement

Ground Granulated Blastfurnace Slag. This material is manufactured to comply with the requirement of BS 6699 : 1992, as well as EN 15167-1 : 2006 and exceeds the minimum strength and fineness requirement by a considerable margin. The total alkali Na2O+0.658 K2O does not exceed

properties of hardened concrete with blast furnace slag

The physical properties of Ground Granulated blast furnace slag (GGBFS) provides advantages to the concrete in fresh state as well as in its hardened state. It is always recommended for a concrete mix design, that would provide us with a denser mass of concrete, i.e. a solid that is free from voids. GGBS play an important role in making the

slag | cement australia

Ground-granulated blast-furnace slag (GGBFS) is produced by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water, to produce a granular product that is then dried and ground into a fine powder. When added to concrete, GGBFS enhances a range of performance characteristics such as the reduction of the

impact of ground granulated blast furnace slag on high

Ground Granulated Blast Furnace Slag (GGBS) GGBS, being the by-product from blast furnace, contains cementitious properties. To develop ultra high-performance concrete, higher cement content (>600kg/m3) is required, which in turn, results in higher heat of hydration

ground granulated blast-furnace slag | springer for

Dec 09, 2017 · Abstract. Since the discovery of the latent hydraulic reactivity of ground granulated blast-furnace slag (ggbfs) by Emil Langen at the end of the 19th century, this material has been used successfully as cement and concrete addition

high strength concrete using ground granulated blast

Ground granulated blast furnace slag is widely used as a mineral admixture to replace partial Portland cement in the concrete industry. As the amount of slag increases, the late-age compressive

ground granulated blast furnace slag

Ground granulated blast furnace slag (GGBFS) is designated in ASTM C 989 and consists mainly of silicates and aluminosilicates of calcium. GGBFS is divided into three classifications based on its activity index. Grade 80 has a low activity index and is used primarily in mass structures because it generates less heat than portland cement

slag cement - lehigh hanson, inc

Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag. The iron is used to produce steel, and the molten slag is

ground granulated blast furnace slag ggbs concrete

GGBS Concrete. GGBS concrete is concrete which contains a significant volume of ground granulated blast furnace slag (GGBS) in the mix as either a supplementary cementitious material or as a replacement for some of the ordinary Portland cement. GGBS concrete behaves in a similar manner to fly ash concrete and affects the setting time, strength

blast furnace slag cement - manufacture, properties and

Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties

slag cement terminology

Slag cement (Ground granulated blast- furnace slag): A hydraulic cement formed when granulated blast-furnace slag is ground to a suitable fineness. Granulated blast-furnace slag: The glassy, granular material formed when molten blast-furnace slag is rapidly chilled
