Coromandel King-Sankar Sakthi- Raasi Gold

Coromandel King, Sankar Sakthi and Raasi Gold are high strength cements to meet the needs of the consumer for high strength concrete. As per BIS requirements the minimum 28 days compressive strength of 53 Grade OPC should not be less than 53 Mpa. For certain specialised works such as prestressed concrete and certain items of precast concrete requiring consistently high strength concrete, the use of 53 Grade OPC is found very useful. 53 Grade OPC produces higher-Grade concrete at very economical cement content. In concrete mix design, for concrete M-20 and above Grades a saving of 8 to 10% of cement may be achieved with the use of above mentioned 53 Grade OPC.

Coromandel King, Sankar Sakthi and Raasi Gold can be used for the following applications :

• RCC works (Preferably where grade of concrete is M-25 and above)
• Precast concrete items such as paving blocks, tiles building blocks etc
• Prestressed concrete components
• Runways, concrete Roads, Bridges etc
• Multistorey buildings

Coromandel-Sankar-Raasi

Coromandel, Sankar and Raasi are the 43 grade OPCs most popular general-purpose cement in the market today. The production of 43 grade OPC is nearly 50% of the total production of cement in the country

The 43 grade OPC can be used for following applications :

• The compressive strength of cement at 28 days when tested as per IS code shall be minimum 43 Mpa. Characteristic strength requirements of this cement are given in the chart.

Blended Cement

Coromandel Super Power, Sankar Super Power and Raasi Super Power are the premium blended cements from THE INDIA CEMENTS LIMITED. It is produced by intergrinding of OPC clinker alongwith gypsum and mineral admixtures. Dedicated to the end user after passing through stringent tests at our R&D laboratory, it ensures durable structures that lasts for generations.

Salient features:

• Strength increases as time passes.
• High durability concrete - protects from corrosion, coastal attack and extreme temperature.
• Ideal cement for resisting aggressive environments like chemical, chloride and sulphate attack.
• Best suited for high performance concrete.
• High fineness - suited for plastering and finishing works.
• Low heat of hydration - Ideal for mass concrete pours and machine foundations
• Equivalent to 53 grade cement.

Applications:

• It is a general purpose cement and can be used with advantage wherever OPC is used.
• Marine structures.
• Mass concrete pours such as in dams etc.
• Highly suited for plastering and finishing works because of it's high fineness
