GGBS from Indorama Cement
Granulated Blast Furnance Slag (GGBS) from Indorama Cement
Limited is granulated blast furnace slag, ground to very high
fineness. Granulated blast furnance slag is obtained during the manufacturing
process of pig iron in a blast furnance. When the molten slag at 1400-1500
degree centigrade is tapped and subjected to a special process of
quenching it, forms granules which is called granulated slag.
This slag when ground to a very high fitness is called Ground Granulated
Blast Furnance Slag. GGBS when used along with OPC in concrete or
mortar mix imparts unique properties to obtain very strong and durable
concrete and mortar mix. ``At Indorama,
we have installed the most modern Vertical Roller Mill from UBE
Japan to grind slag to very high fineness (upto 4500cm2/gm) while
maintaining uniform particle size distribution. This enables us
to supply you truly world class GGBS. The advantages of using GGBS
are, there is reduced heat of hydration and hence there are no thermal
cracks, improved workability, improved resistance to chloride ingress,
protection from sulphate attacks, protection from Alkali-Aggregate
reaction, prevention of corrosion of rei0nforcing steel, impermeability
and improved long term strength", says R K Maheshwari,
Senior Vice-President (Works) of Indorama Cement Limited.
``Due to these advantages, GGBS imparts
much needed durability to the concrete or mortar. It comes in handy
for all types of constructions in coastal areas. It is also an ideal
material for use in high grades of concrete, where use of cement
replacement materials is required to control the danger of shrinkage
cracks as well as thermal cracks. Hence it is also called a Performance
Enhancing Compound. GGBS reacts with excess Ca(OH)2 present
in concrete/ mortar to produce extra C-S-H gel. This gel imparts
various properties to concrete/ mortar making it durable,''
claims R K Maheshwari, Senior Vice-President (Works) of Indorama
Application of GGBS:
Ideal for use in all grades of concrete. For use in residential,
commercial as well as industrial structures, especially in coastal
* Mortar for plastering in residential, comercial as well as industrial
structures in coastal areas.
* Foundations of residential, commercial as well as industrial structures
where sulphates and chlorides are high.
* Infrastructure projects where high strength and high performance
concrete is required.
* Marine constructions like ports, harbours, and jetties.
* Bridges and fly-overs, Roads and pathways.
* Dams and other mass concrete works.
* Concrete products for shore protection.
* Water treatment plants and water retaining strong structures.
* Effulent treatment plants and sewage treatment plants.
* Cement based products like tiles, pipes
Mumbaika Commando Special Portland Cement, manufactured
by Indorama Cement Limited is used in concretising a surface. It
gives the surface a smooth and crack free look. Other properties
are also immune to chemical reactions, load bearing capacity is
high, all-weather sustainability and time defying durabilities.
"Mumbaika Commando has a unique Performance
enhancing compound which works wonders. It ensures continued hydration
that produces extra C-S-H gel which makes the concrete, compact,
stronger and impermeable. This higher impermeability of concrete
lends it better immunity from chemical attacks and helps it weather
effortlessly for longer periods of time. Not only that, but the
presence of a performance enhancing compound strengthens the concrete
with time and improves its load bearing capacity,'' said
Mumbaika Commando Special Portland Cement is also used in plastering.
``Like a well trained Commando,a plastering
coat of Commando is truly tough and able to sustain ambient saline
weather hazards of coastal areas. Of course, it is savvy enough
to withstand extreme weather conditions. Commando spreads evenly,
sets firmly and protects structure against leaks even in torrential
rains... year after year. Easy to mix, mortars made from Commando
behave magically in the hands of masons, both seasoned and begginers,''
