IS 17354:2020 Part 1 is the Indian Standard (BIS) for methods of test for recycled aggregates - part 1: density, water absorption, percentage of crushed particles and material finer than 75 micron sieve. This standard outlines the laboratory test methods for determining the mechanical and durability properties of recycled aggregates from construction and demolition waste. It details procedures for measuring abrasion value, impact value, crushing value, and soundness to assess their suitability for use in construction.
Describes methods for determining density, water absorption, percentage of crushed particles, and material finer than 75-micron sieve for recycled aggregates.
! The test procedures are largely adapted from IS 2386 (Part 4) which is for natural aggregates; however, this standard accounts for the specific characteristics of recycled materials.
! Accurate and representative sampling as per IS 2430 is critical due to the inherent heterogeneity of recycled aggregates.
! Test results from this standard are essential inputs for designing concrete mixes with recycled aggregates as per guidelines like IS 10262 and for checking conformity with IS 383.

Key Differences
≠The primary sieve for determining fines content in IS 17354 is 75 microns (0.075 mm), which aligns with US practice (ASTM No. 200 sieve). European standards like EN 933-1 specify a 63-micron (0.063 mm) sieve for this purpose.
≠IS 17354 is a dedicated standard formulated specifically for recycled aggregates from Construction and Demolition (C&D) waste. In contrast, EN 1097-6 and ASTM C127/C128 are general standards for all aggregates, which are then applied to recycled materials without specific clauses addressing issues like attached mortar.
≠Minimum test sample masses for density determination can vary. For a 20 mm nominal maximum aggregate size, IS 17354 (via IS 2386-3) requires a 2 kg sample, whereas ASTM C127 specifies a 3 kg sample.
≠The definition of a fractured particle can be more detailed in international standards. ASTM D5821 allows for classification based on one, two, or more fractured faces, while IS 17354 generally classifies based on the presence of 'at least one crushed face'.
Key Similarities
≈The fundamental principle for determining density and water absorption is identical, based on Archimedes' principle and the concept of a Saturated Surface-Dry (SSD) condition.
≈The methodology for determining the percentage of material finer than the specified sieve (fines content) is consistently based on washing a sample over the fine sieve and calculating mass loss after drying.
≈The procedure for achieving the Saturated Surface-Dry (SSD) state for coarse aggregates is very similar, involving soaking the sample for approximately 24 hours and then drying its surface with an absorbent cloth until no free water is visible.
≈The general procedure for determining the percentage of crushed particles involves the manual separation and visual inspection of a representative sample to classify particles as crushed or uncrushed, followed by a calculation based on mass.

⚠ Verify details from original standards before use
To provide standardized methods for testing the strength (abrasion, impact, crushing) and durability (soundness) of recycled aggregates.
Does this standard give acceptable limits for the test values?+
No, this is a testing method standard. It only specifies how to perform the tests. Acceptable limits are provided in material specification codes like IS 383 or in project-specific requirements.
What does the 'Aggregate Abrasion Value' test signify?+
It indicates the aggregate's resistance to wear and abrasion, which is crucial for applications like road surfaces and floor screeds. The test is performed using the Los Angeles machine (Clause 4).
How does this Part 2 relate to Part 1 of IS 17354?+
Part 1 covers methods for determining physical properties like particle size distribution, water absorption, density, and flakiness index, while Part 2 covers mechanical properties and durability.
