The ground granulated blast furnace slag (GGBFS) is a by-product 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.

Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from ...

A premature ventricular contraction (PVC) is a too-early heartbeat that originates in the ventricles and disrupts the heart's normal rhythm. The pattern is a normal beat, an extra beat (the PVC), a slight pause, then a stronger-than-normal beat. The heart fills with more blood during the pause following the PVC, giving the next beat extra force.

This is one reason why slag cement can be used in much larger amounts. Both are used as a replacement for a portion of the portland cement. Slag cement replaces as much as 50 percent in normal concrete (and up to 80 percent in special applications such as mass concrete). Fly ash is usually limited to 20 or 30 percent.

When slag is added, its silicates react with C-H, forming additional C-S-H gel and creating denser, harder cementitious paste with increased strength [22]. However, the rate of hydraulic reactivity of granulated blast furnace slag is slower than for ordinary Portland cement; thus, slag with greater fineness is usually used …

Carbide slag, also known as calcium carbide residue (CCR), is a by-product of the hydrolysis of calcium carbide. It is commonly generated from the industrial production of ethylene, polyvinyl chloride (PVC) and other products as a solid waste. Currently, it has no value for recovery and is commonly landfilled. At some Chinese plants, this slag is used as an alternative raw material for cement ...
