The exact composition of slag varies over a range. In general, factors that determine the suitability of slag for usage in composite cement mainly include the fineness of grinding, glass content and the chemical composition. Fineness; Like most of other cement materials, the reactivity of slag is influenced by its surface area.
· Slag cement is not recommended for appliions, such as swimming pools, where concrete will remain continuously wet, because this inhibits oxidation. Factors that may impact greening include a low w/cm ratio that results in low permeability concrete, extended wet curing, shady exposure, and a steel trowelled densified surface. Although it is preferable to wait for natural oxidation to ...

· Common slag treatment process in Japan is shown in Figure [81]. About 80% [79] of BF slag is quenched by water spray and the quenched BF slag sand produced is used mainly for cement, concrete and civil engineering resources. The rest is cooled by field air cooling and the slow cooled slag is used as a resource for road construction ...
Usb2 Process For The Production Of Portland Slag. Accordingly, the present invention provides an improved process for the production of Portland slag cement using granulated blast furnace slag, which comprises viii forming of cement clinker by known process,.
The ground granulated blast furnace slag (GGBFS) is a byproduct of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree Celsius. The process is carried out in a blast furnace.
