Introduction of OPC

Which Grade Cement Is Used for Slab

Types of Cement Grades

• OPC 33 Grade Cement
• OPC 43 Grade Cement
• OPC 53 Grade cement

OPC (Ordinary Portland Cement) 33 Grade Cement

• 3 days compressive strength = 16 N/mm2
• 7 days compressive strength = 22 N/mm2
• 28 days compressive strength = 33 N/mm2

Properties of 33-Grade Cement

• This grade of cement has high workability and is mainly used for masonry work and for plastering work.
• The initial strength of 33 Grade Cement continues to gain even after 28 days.
• The heat of hydration of 33 Grade Cement is lower as compared to the 43 grade and 53-grade cement.

Uses of 33-Grade Cement

• It is widely used in plastering work.
• It is also used for the brickwork of walls.
• In the tiling work.
• It is generally used for work, which required low compressive strength of below M20.

OPC (Ordinary Portland Cement) 43 Grade Cement

• 3 days compressive strength = 23 N/mm2
• 7 days compressive strength = 33 N/mm2
• 28 days compressive strength = 43 N/mm2

Properties of 43-Gradee Cement

• It has low chloride content, so it doesn’t cause corrosion of steel reinforcement.
• It gives good workability of concrete.
• The initial strength of 43 Grade Cement continues to gain even after 28 days.
• The heat of hydration of 43 Grade Cement is medium.
• This will give a better surface finish to the structures.
• It is moderately sulfate resisting.

Uses of 43 Grade Cement

• It is used in the preparation of Ready Mix Concrete (RMC).
• It is used for PCC and RCC work.
• It is used in the construction of RCC bridges.
• For Construction of Silos and Chimneys.
• It is used for finishing of all types of structures like buildings, bridges, roads, and water retaining structures.
• It is used in precast and prestressed concrete.
• It is also used in Ship form Construction.
• It is used in the construction where a grade of concrete up to M30.

OPC (Ordinary Portland Cement) 53 Grade Cement

• 3 days compressive strength = 27 N/mm2
• 7 days compressive strength = 37 N/mm2
• 28 days compressive strength = 53 N/mm2

Properties of 53 Grade Cement

• It is a Sulphate resisting cement.
• It has low chloride content.
• It can be used in speedy Construction.
• It saves shuttering cost due to early removal.
• The initial strength of 53 Grade Cement continues to gain even after 28 days.

Uses of 53 Grade Cement

• It is used the construction of concrete sleepers for Railways.
• It is used in pre-stressed girders.
• The 53-Grade Cement achieves early strength.
• It is used in industrial buildings roads and runways.
• It is used in the construction of RCC bridges and precast concrete.
• Generally used for M25 and above concretes.
• It is used in the construction of all RCC components like a beam, columns, footings, and slabs.
