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.

HistoryThe 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 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.

Subsidiary companiesThe companies of the Mehta Group include, but are not limited to the following:

India Saurashtra Cement Limited – Ranavav, Gujarat,

India Gujarat Sidhee Cement Limited – Sidheegram,

HATHI CEMENT:-

Introduction:-

The Mehta Group is multi-activity, multi discipline global enterprise spanning four continents - Asia, Europe, North America and Africa. The Group's business interests cover a wide and varied spectrum, which includes cement, building materials, sugar, packaging, electrical cables, engineering, consultancy, management & financial services, international trade, floriculture and horticulture.

Meaning and Definition:-I. Developed in 1980

II. Concrete which flows to a virtually uniform level under the influence of gravity without segregation, during which it de-aerates and completely fills the formwork and spaces

between the reinforcement without any need for induced compactions.

III. Obtained by,

Limiting the w/c ratio. Adding an effective

plasticizer. Increasing sand-

aggregate ratio. Adding viscosity

enhancing admixtures.

About:-

The Indian Arm of the group comprises of "Saurashtra Cement Limited" (SCL), marketing cement under the brand name "HATHI". Saurashtra Cement Limited is The Company is an ISO 9001:2008, ISO 14001:2004 and ISO:

18000:2007 certified company which manufacturers Portland Pozzolana Cement (PPC), Ordinary Portland cement (OPC 53 grade, 43 grades), SRPC types of cement and clinker. The company's products comply with world class quality standards. SCL is a recognized Export House and has won the Indian cement industry's prestigious national award for 'Energy Efficiency.'

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 (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.

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 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 business.

Necessity:-

Mix Design:-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.

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.

• 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:-• 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.

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• Super-plasticizers to be added towards the end of mixing to getBetter flow ability

• Admixtures to be dispensed together with or in the mixing water.HATHI CEMENT COMPETITIORS :-
