ACC
manufactures the following types of cement,
in addition to which, it provides Bulk Cement
and Ready Mix Concrete.
Ordinary Portland Cements
ACC Cement is the most commonly used cement
in all constructions including plain and reinforced
cement concrete, brick and stone masonry, floors
and plastering. It is also used in the finishing
of all types of buildings, bridges, culverts,
roads, water retaining structures, etc.
What is more, it surpasses
BIS Specifications (IS 8112-1989 for 43 grade
OPC) on compressive strength levels.
ACC Cement is marketed in
specially designed 50 kg bags.

This is an Ordinary Portland Cement which surpasses
the requirements of IS: 12269-53 Grade. It is
produced from high quality clinker ground with
high purity gypsum.
ACC 53 Grade OPC provides
high strength and durability to structures because
of its optimum particle size distribution, superior
crystalline structure and balanced phase composition.
It is available in specially
designed 50-kg bags.

Blended Cements
Fly-ash based Portland Pozzolana Cement
This is a special blended
cement, produced by inter-grinding higher strength
Ordinary Portland Cement clinker with high quality
processed fly ash - based on norms set by the
company's R&D division. This unique, value-added
product has hydraulic binding properties not
found in ordinary cements.
It is available in specially
designed 50-kg bags.
What is special about
ACC Fly-ash based PPC?
ACC Fly-ash based PPC is made by intergrinding
high strength clinker with specially processed
flyash. This imparts a greater degree of fineness
to ACC Fly-ash based PPC cement, improved workability
properties while mixing, and makes concrete
more corrosion resistant and impermeable. All
of this makes for better long-term strength
and improved corrosion resistance and therefore,
greater life for your constructions. ACC Fly-ash
based PPC is an eco-friendly cement
What are the advantages
of using ACC Fly-ash based PPC ?
In concrete made from ordinary cements, moisture
reacts with calcium hydroxide in concrete to
form calcium bicarbonate, which leaches out
of the concrete, leaving pores that reduce its
strength. ACC Fly-ash based PPC has ingredients
which react with calcium hydroxide to form CSH
gel, to provide additional strength, which actually
makes the concrete grow in strength over the
years. It also produces less heat of hydration
and offers greater resistance to the attack
of aggressive waters than normal Portland cement.
Can ACC Fly-ash based
PPC be used for all jobs in construction?
ACC Fly-ash based PPC easily replaces OPC and
provides additional advantages for practically
all types of construction applications - commercial,
residential, bungalows, complexes, foundation,
columns, beams, slabs and RCC jobs. It is especially
recommended for mass concreting work, and where
soil conditions and the prevailing environment
take heavy toll of constructions made with ordinary
cements.
How does ACC Fly-ash
based PPC stand up to corrosive environments?
Due to its inherent characteristics, ACC Fly-ash
based PPC makes very corrosion resistant concrete
that is superior to concrete made with OPC.
It is more impermeable to oxygen, CO2, chlorides,
etc. Leaching of alkalis is reduced and the
alkaline environment around steel is maintained.

This is a slag-based blended cement that imparts strength and durability to all structures. It is manufactured by blending and inter-grinding OPC clinker and granulated slag in suitable proportions as per our norms of consistent quality. PSC has many superior performance characteristics which give it certain extra advantages when compared to Ordinary Portland Cement
It is available in specially designed 50-kg bags.
What is special about ACC PSC?
Compared to OPC, ACC PSC imparts some important
additional advantages
- Reduction in free lime leaching.
- Ultimate higher strength.
- Improved workability, reduced bleeding as
well as segregation and corrosion.
- Denser, less permeable concrete, and mortar.
- Better resistance to sulphates, chlorides,
and CO2 and alkali-aggregates reaction.
- Less heat, reduced plasticity and drying
shrinkage.
- Increased static modulus of elasticity.
- Increased serviceability with less deflection
of members and micro cracks and reduced cost
of construction and maintenance.
All these factors make for
a strong, durable, and longer lasting construction.
ACC PSC benefits the structure, protects the
environment by reducing CO2 emissions and helps
conserve energy. Which is why it is often referred
to as an eco-friendly cement.
The Federation International
de la Precontrainte (FIP) Guide to Good Practice
for "concrete constructions in hot weather,"
states that if concrete is likely to be exposed
to an environment of sulphate-bearing water
or soil, it is preferable to use a proven type
of blended cement containing ground granulated
blastfurnace slag. Concrete made with ACC PSC
has a higher density than concrete made with
OPC, and hence it improves the durability of
concrete structures.
It can, therefore, be used
for all purposes where OPC or PPC is used.
