5. The Mehta Group of Companies commonly
referred to as the Mehta Group is a conglomerate
based in Mumbai, India, with subsidiaries in the
United States, Canada, Kenya and Uganda. The
group employs in excess of 15,000 people
worldwide and has an asset base in excess of
US$350 million, as of April 2010. The group's
businesses include investments in sugar, cement,
packaging, floriculture, engineering, cables,
consulting, management, insurance, International
Trade and International Finance.
6. History
The group owes its foundation to Nanji Kalidas
Mehta (1887–1969). He was born in India in the
late 19th Century. In 1900, at the age of 13 years,
he migrated to Uganda and started a series of
businesses that included a tea plantation, a cotton
ginnery, a sugarcane plantation and a sugar
factory.
During the 1930s, having established himself in
Uganda, Mehta began operations in India. He set
up a textile mill and ginning factory in Porbandar,
Gujarat, and a trading company in Bombay. Later,
a cement plant (Saurashtra Cement Limited) was
established in 1956.
In 1972, Idi Amin, then leader of Uganda, expelled
all Asians from the country; all of the group's
Ugandan possession were surrendered, many to
the government-controlled Uganda Development
Corporation. The group concentrated on their non-
African businesses; setting up a consultancy in
India and a plastics plant in Canada becoming a
truly International conglomerate during the 1970s.
In 1979, Amin was removed from power and the
7. group was invited back into Uganda to repossess
their assets.
During the 1980s the Agrima Consultancy wing of
the group expanded to Ethiopia, Cameroon, Sudan,
Burundi, Nigeria, Nepal, Sri Lanka and Myanmar.
The group rehabilitated all their Ugandan
businesses during this period. A second cement
plant was started in India; the Gujarat Sidhee
Cement Limited.
During the 1990s the group entered the financial
area by establishing Transafrica Assurance
Company Limited. During this period, the cement
factories in India were expanded and modernized.

About Self Compacting Concrete
(SCC). Durable Construction with
Hathi Cement:-
Saurashtra Cement Limited (SCL) is the flag ship
company of the Mehta Group, formed in 1956. SCL is
one of the leading players in the Indian cement
industry, manufacturing Portland Pozzolana Cement
12. (PPC), Ordinary Portland cement (OPC) and Sulphate
Resisting Portland cement (SRPC).
SCL markets cement under the brand name "HATHI
CEMENT". The product is marketed in 50 kg HDPE / PP
/ paper bag, in bowsers and in jumbo bags (1 MT) as
per user need. The product is preferred for its proven
durability and is noted in the market for its special
greenish tinge and superior finish on the external
surface.
SCL's plant at Ranavav, located in Gujarat state has a
capacity of 1.5 MTPA. The plant is a modern energy
efficient dry process plant comparable to
international standards and makes use of latest
machinery sourced from reputed international
companies. The plant offers locational advantages
because of its proximity to the Porbandar and
Veraval/Okha ports, rail net work and is close to
highways. SCL thus has competitive access to the
domestic markets and also to the large export
markets in the Africa, Middle East countries, Sri Lanka
etc. by the economical sea route.
13. SCL's modernization implemented in the recent years
has paid results. State-of-the-art equipment and
control systems installed have led to capacity
enhancement. The new captive power plant which can
be operated with different fuels like coal, pet coke &
lignite has improved the overall performance by way
improved reliability, consistency, better cost control
and improvement in quality and lower emission
levels.
Our Policy is to produce and serve our customers
with consistent quality clinker and cement
conforming to applicable statutory and
14. regulatory requirements and / or customer's
specification in stipulated delivery period to their
satisfaction.
We are committed to implement the quality
management system as per ISO 9001: 2008 and
creating an environment where in every
employee contributes towards continual
improvement and innovation in all aspects of our

17. To be designed in such a way to have high
fluidity, least or no segregation, and low risk
of blocking.
High cement paste volume, low coarse
aggregate and water content, and proper
dosage of super-plasticizer.
The sand/coarse aggregate ratio is about 1,
which is slightly higher than that used for
control concrete.
Refer Specification and Guidelines for Self-
Compacting Concrete- EFNARC for more
details.
Mix Design:-
1. Coarse Aggregate:-
Size is limited to 20 mm.
Crushed aggregates tend to improve the strength due
to interlocking angular particles, also, reduce the flow-
ability.
18. Rounded aggregates improve the flow due to less
internal friction and less surface area per mass.
Gap graded aggregates better than well graded
aggregates.
Amount less than 50% by weight of total
aggregates (C.A. + F.A.)
Normal range is 700-800 kg/m3 of concret.
By volume, content is 50-60% of the total
aggregate volume.
2. Fine Aggregate:-
• Size is smaller than 4.75 mm and up to 0.075 mm.
• Finer than in normal concrete.
• Weight of sand to that of coarse aggregates in range of
1.1 to 1.6.
• Ratio may be less if filler dust is used.
• Volume should be 40-50% of the mortar/paste volume.
3. Dust/Fines:-
• Size is smaller than 0.075 mm.
19. • Decided to be used in absence of use of various
SCMs.
• Amount in absence of SCMs to be used is 400-600
kg/m3 of concrete.
4. Cement:-
• Amount same as to be used for normal concrete.
• Use of fly ash, slag, silica fume is very essential.
5. Water:-
• W/c ratio to be less than 0.4 for durability
considerations.
• Free water should be less than 200 L per m3 of
concrete.
• Amount in absence of SCMs to be used is 400-600
kg/m3 of concrete.
• Water powder ratio by volume is generally 0.8-1.1.
6. Chemical Admixtures:-
20. • Super-plasticizers promote workability retention with a
mechanism of electrostatic repulsion and steric
hindrance.
• Viscosity modifiers increase resistance to segregation
while still maintaining high fluidity, allowing concrete to
flow through narrow space.
Mix Design Approach:-
1. Evaluate the water demand and optimise the flow
and stability of the paste.
2. Determine the proportion of sand and the dose of
admixture to give the required robustness.
3. Test the sensitivity for small variations in quantities
(the robustness).
4. Add an appropriate amount of coarse aggregate.
5. Produce the fresh SCC in the laboratory mixer,
perform the required tests.
6. Test the properties of the SCC in the hardened state.
7. Produce trial mixes in the plant mixer.
22. SCC placed using a Pump
Production, Placing and Quality
Control:-
_ Mixing of Concrete
• Common Mixers, force action mixers are
more preferred
_ Free fall plant and truck mounted mixers
_ Forced Action mixers
• Mixing Time is longer as compared to
control concrete
23. • Super-plasticizers to be added towards the
end of mixing to get
Better flow ability
• Admixtures to be dispensed together with
or in the mixing water.
