Engineering Benefits of GGBS in Concrete
The significance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material. GGBS being a waste material, it needs a proper method for disposal. So incorporating this waste material of iron in concrete can reduce the depletion of conventional concrete components…
What is GGBS? Its Advantages and Disadvantages
What is Ground Granulated Blast Furnace Slag (GGBS)? The ground granulated blast furnace slag (GGBS) 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 the iron ore, limestone, and coke at…
Chemical Properties and Physical Properties of Silica Fume
Silica fume, also known as microsilica, is an extremely fine non-crystalline polymorph of silica and is produced in electric arc furnace (EAFs) as a byproduct of silicon and ferrosilicon alloy production. While the first trials of silica fume as an additive in concrete were in the 1950s, at that time…
