What is the standard unit weight of RCC?

2500 kg/m³ (or 25 kN/m³). This value includes the mass of the reinforcing steel. (Table 1)

What is the unit weight of brick masonry?

For common burnt clay bricks, it is 1920 kg/m³. Values for other types of bricks and blocks are also provided. (Table 1)

Where can I find the unit weight of steel?

The unit weight for structural steel, rolled steel, and steel castings is listed as 7850 kg/m³. (Table 1)

Does this code provide material strength values?

No, this standard focuses on physical constants like density and thermal properties, not mechanical strength (e.g., compressive or tensile strength). For strength values, refer to material-specific codes like IS 456 or IS 1786.

This standard provides a comprehensive list of material constants for various common building materials. It covers physical properties such as mass density (unit weight), bulk density, thermal properties (conductivity, expansion), and acoustic properties, serving as a fundamental reference for design and estimation.

Practical Notes

This code is the primary source for material unit weights used in dead load calculations as per IS 875 (Part 1).

The values provided are standard averages. For critical applications or specific proprietary materials, always refer to the manufacturer's data or conduct specific tests.

While this code gives the density of concrete, IS 456 is the governing code for all other aspects of concrete design and construction.
