Granulated blast furnace slag having the composition within the following ranges generally meets the requirements for its use in making blast furnace slag cement.It should contain less than 1.0% Fe 2 O 3 and 1%–3% Na 2 O + K 2 O. Some uncertainty was raised in the past concerning the mobilization of sulphur present as sulphide in the slag, its …
Four important methods for use of granulated slag, where it maintains its separate identity, and is a cementitious component, are: Ground glassy slag is mixed with hydrated lime as the activator; the glassy slag is ground with burned gypsum or anhydrite and small amounts of Portland cement or lime; ground glassy slag and Portland …
Blast furnace slag (BFS) is the main by-product of iron making and is produced in large amounts worldwide. To improve energy use, it is necessary to understand the thermal behaviour of slags under differing compositions at varying temperatures. ... Concrete, cementitious additive, can be mixed with Portland cement clinker to make a …
There are also some studies on the substitutions of cement by ground granulated blast furnace slag (GGBFS) [5,17,18,19,20], even getting up to 80% of the cement removed by this type of slag. Khatib et al. replaced up to 80% of cement by GGBFS making different substitutions. Good results were obtained in the substitutions …
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...
Blast Furnace Slag Concrete with Brick Waste Addition Baali, Naceri, Rahmouni and NouiMehidi (2011) investigated the possibility to make a mortar with ternary sand (natural and artificial fine aggregates).
