IS 456-2000
Designation of Concrete Mixes
- IS 456-2000 is the code for the design and construction of reinforced concrete structures.
- It has designated concrete mixes into a number of grades such as M10, M15, etc.
Explanation of Grades
- The designation M10, M15, etc., refers to the compressive strength of concrete mix after 28 days of curing.
- For example, M10 means the concrete mix has a characteristic compressive strength of 10 MPa or 10 N/mm².
Usage in Construction
- Different grades of concrete mixes are used for different applications based on the required strength and durability.
- Higher grade mixes like M20, M25, etc., are used for structural elements like beams, columns, slabs, etc., where high strength is required.
- Lower grade mixes like M10, M15, etc., are used for non-structural elements like paving blocks, plastering, etc.
Importance of Designation
- The designation of concrete mixes into grades helps in ensuring the desired strength and durability of concrete in various construction applications.
- It provides a standardized way of specifying concrete mixes to achieve the desired performance characteristics.
