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.

Granulated Blast Furnace Slag - an overview ...
However, early attempts at using blast furnace slag in cement production were not successful. Poor performance of the initial slag cement was often due to poorly granulated slag and accelerators being added in large quantities without consideration of the long-term effects [7]. This even led to slag being prohibited in cement specifications.

25-4-2020 · Cement - Cement - Slag cements: The granulated slag made by the rapid chilling of suitable molten slags from blast furnaces forms the basis of another group of constructional cements. A mixture of portland cement and granulated slag, containing up to 65 percent slag, is known in the English-speaking countries as portland blast-furnace (slag) cement. The German …
Blast Furnace Slag Cement - Manufacture, …
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.
Ground Granulated Blast Furnace Slag - an …
Slag. 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).
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.

Ground Granulated Blast Furnace Slag (GGBS) - …
Granulated Blast Furnace Slag is obtained by rapidly chilling (quenching) the molten ash from the furnace with the help of water. During this process, the slag gets fragmented and transformed into amorphous granules (glass), meeting the requirement of IS 12089:1987 (manufacturing specification for granulated slag used in Portland Slag Cement).
Ground Granulated Blast-Furnace Slag | CEMEX UAE
Making cement is energy intensive, generating up to 176 kg CO 2 for each tonne of concrete manufactured. Because Ground-granulated blast-furnace slag (GGBS or GGBFS) is a lower carbon building material, its considerably more environmentally friendly.
