Ground granulated blast furnace slag is produced by pulverizing granulated blast furnace slag produced by blast furnaces as a by-product of the iron-making process. This hydraulic admixture is popular for use as raw material for Portland blast furnace slag cement admixture for raw concrete and other applications.
Written to meet the requirements of engineers working in construction and concrete manufacturing Mineral Admixtures in Cement and Concrete focuses on how to make more workable and durable concrete using mineral admixtures.In particular it covers pulverized fuel ash PFA blast furnace slag BFS silica fume SF rice husk ash RHA and metakaolin MK as well as some new admixtures.
Mar 29 2017 Book Description. Written to meet the requirements of engineers working in construction and concrete manufacturing Mineral Admixtures in Cement and Concrete focuses on how to make more workable and durable concrete using mineral admixtures.
Mar 26 2020 The present work reviews the various mineral admixtures used in concrete which modifies the concrete properties. In this study cement is partially or completely replaced by different mineral admixtures such as fly ash silica fume rice husk ash Ground Granulated Blast Furnace Slag palm oil fuel ash and metakaolin.

Types of concrete mineral admixtures. Fly ash finely ground blast furnace slag powder steel slag powder pozzolan desulfurized gypsum powder phosphogypsum powder tuff powder basalt powder glass ceramic powder sintered brick powder limestone powder granite powder quartz powder etc.
Blast furnace slag from Tinec ironworks. Unlike the blast furnace slag deposited near Kladno Tinec slag was rapidly water-cooled resulting in a high content of glassy components that make the slag a suitable admixture to concrete. For this study slag samples were also disintegrated and finely ground using high-speed mills. 2.3.10.
Cement and Concrete Mineral Admixtures concentrates mostly on natural pozzolans fly ashes ground granulated blast furnace slag silica fume and limestone powder namely the most commonly used.
grade with Ground-granulated blast- furnace slag and Fine aggregate by Marble slurry a mineral admixture in concrete. GGBS is produced by quenching molten iron slag in water or steam to produce a glassy granular product that is then dried and ground into the fine powder.
Concrete Admixtures Mineral. GROUND GRANULATED BLAST - FURNACE SLAG 711-12 Following is a list of slag cement suppliers approved to supply the indicated brand of GGBFS to Department work in accordance with the current provisions of both GROUND GRANULATED BLAST.
Jul 29 2020 The most common mineral admixtures are Fly ash. Ground Granulated Blast furnace Slag GGBS Rice husk ask. Metakaolin. Silica fume. Sugarcane bagasse or straw ash. Palm oil fuel ash. The mineral admixtures are added majorly to modify the strength of the concrete and increase the compressive strength..
Blast furnace slag is a by-product of the extraction of iron from iron ore. Coke and limestone are added as fluxes inside the blast furnace.
Mineral Admixtures in Concrete Types of Mineral Admixtures. Cementitious These have cementing properties themselves.
Aug 20 2017 In some studies ground granulate blast furnace slag-steel slag composite binder was used as a composite mineral admixture and shown to prolong the setting time of the cement improve the fluidity of fresh concrete refine the pore structure of hardened paste and result in a satisfactory compressive strength for the concrete 14 15.
can be produced using mineral admixture with steel slag powder and blast furnace slag so the recycling of steel slag can bring enormous benefits and environ-mental benefit to whole society.9 6. Ground granulated blast furnace slag is commonly used in combination with Portland cement in concrete for many applications1011 7.
