IS 3182: Physical Requirements for Broken Brick Fine Aggregate

1. Grading (Clause 3.1 & Table 1)

Fine aggregate shall conform to the following sieve analysis (% passing by mass):

• Note: 100% passing 4.75 mm sieve (Clause 2.2).

2. Physical Properties (Clause 3.2 & Table 2)

3. Rounding Off (Clause 0.4)

• Test results shall be rounded as per IS 2-1960, keeping significant digits consistent with specified values.

IS 3182 Sampling - Key Points & Specifications

• Sampling Method: As per IS 2430-1969 (Specification for common burnt clay bricks).
• Aggregate Sampling: Follow IS 2386 series for test methods on aggregates.

Table: Requirements for Broken Brick Fine Aggregate (Clause 3.2)

Notes:

• Rounding off: Final test results should be rounded per IS 2-1960, matching significant places of specified values.
• Sampling ensures representative material for testing to verify compliance with standards.

IS 3182: Compliance Criteria for Broken Brick Fine Aggregate

Key Rounding Rule (Clause 0.4)

• Final test values must be rounded per IS 2-1960.
• Retain the same number of significant figures as specified in the standard.
