Abstract. Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. When iron-ore, coke and limestone melt in the blast furnace, two products are produced—molten …
In the view of negative aspect of poor carbonation resistance of slag, the current study is aimed to improve the compressive strength of concrete with reduced slag content by adopting novel mixing methodology. Notations. GBS 2.5: 2.5% weight of cement replacement by blast furnace slag. GBS 5: 5.0% weight of cement replacement by …
ASTM C125 as a "granulated blast-furnace slag that has been ground to cement fineness, with or without additions, and that is a hydraulic cement" (Slag Cement Association, 2021, p. 5). Slag is an SCM and is also a waste material from iron ore production as illustrated in Figure 1. Therefore, slag
blended mechanically with cement at the cement mill to make ASTM C595, Type IS, Portland blast-furnace slag cement, or it can be added at the concrete plant to make slag concrete. The ingredients, proportions and physical requirements of Type IS cement are listed in ASTM C595, "Standard Specification for Blended Hydraulic Cements."
Consequently, construction waste aggregates and blast furnace slag can be used to improve the mechanical properties, workability, and chemical resistance of the conventional concrete mixtures. Since the construction waste and blast furnace slag wastes are available in vast amounts in Turkey, it is economically and environmentally …
The properties of blast furnace slag cement are as follows, The density of slag cement is 3.04 g/cm³. While the setting time is 60 minutes initially, the final setting time of this cement is 600 minutes. The compression strength of Blast furnace slag cement is 23.5 N/mm2 for three days, 36.1 N/mm2 for seven days, and 62.4 N/mm2 for 28 days.
JSW Portland Slag Cement (PSC) is a blended cement, wherein some portion of OPC is replaced with Ground Granulated blast furnace slag (GGBS), to make the structures more lasting. According to the EPD data, global warming potential of PSC is 325.14 kg CO 2 equivalent. As a result of lower clinker factor due to substitution with slag, the global ...
In some studies, it has been demonstrated that using a composite mineral admixture known as ground-granulated blast-furnace slag-steel slag composite …
Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties. In this …
Ground granulated blast furnace slag is an eco-friendly material with regard to its production process and usage. In this study, slag cement (SC) is used to prepare different slag cement mortar (SCM) mixes to study mortar microstructure perspectives, physiochemical properties, mechanical properties and durability …
One of these materials is the " blast furnace slag ". So, what happens is you reduce the amount of cement; instead of using cement, now we can use less amounts. The equation for example turns to: concrete = % of normal cement + % of blast furnace slag + water + fine aggregate + coarse aggregate + admixtures.
Various types of slag are produced: - Blast-furnace slag—The nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other …
Air-cooled blast furnace slag. Angular, roughly cubical, and rough, porous, or smooth textures when finely ground. High water absorption up to 6%. ed blast furnace slag.
