Aggregate Testing Services
Ensuring the quality, consistency, and durability of construction materials for long-lasting performance.
Why Aggregate Testing Matters
Precision for Durable Construction
**Aggregate Testing** is a vital process in the construction industry that ensures the quality, consistency, and performance of materials used in concrete, asphalt, and other structural applications. Aggregates—such as sand, gravel, and crushed stone—play a major role in determining the strength and durability of construction projects.
Through our advanced laboratory services, key properties like **particle size distribution, specific gravity, water absorption, and crushing strength** are thoroughly evaluated. We help clients confirm that their materials meet the necessary quality standards and engineering requirements, ensuring superior material quality and durable, long-lasting construction performance.
Key Tests and Methodologies
We offer comprehensive testing in compliance with major standards (IS, ASTM, BS) to deliver precise and reliable results across these critical areas.
Specific Gravity and Water Absorption
Measures the strength and quality of the material. Higher water absorption indicates greater porosity, which is generally undesirable.
Test Method: IS: 2386 (P-3)1963, ASTM C 127, 128-2007
Particle Size Distribution (Sieve Analysis)
Determines the percentile quantity of particles of known diameter within a sample. Critical for material performance.
Test Method: IS: 2386 (P-1) 1963, ASTM C136-2006, IS: 383-1970
Aggregate Crushing Value (ACV)
Measures the resistance of an aggregate to crushing under a gradually applied compressive load.
Test Method: IS: 9376-1979, IS: 2386 (P-4)1963
Los Angeles Abrasion Test (L.A. Abrasion)
Indicates aggregate toughness and abrasion characteristics, ensuring the material resists degradation in Hot Mix Asphalt (HMA).
Test Method: IS: 2386 (P-4) 1963
Impact Value
Indicates the aggregate's ability to resist sudden crushing (impact). Lower figures indicate a stronger aggregate.
Test Method: IS: 2386 (P-4) 1963, ASTMC 131-2006
Flakiness and Elongation Index
Determines the percentage of flat and thin particles, which can affect workability and strength.
Test Method: IS: 2386 (P-1) 1963
Chloride and Sulphate Content
Assesses the aggregate's contribution to total chloride and sulphate content in a concrete mix, vital for preventing early corrosion of steel reinforcement.
Test Method: IS: 4032-1985
Alkali Aggregate Reactivity (AAR)
Tests for reactions between highly alkaline cement paste and non-crystalline silicon dioxide, which can cause expansion and spalling of concrete.
Test Method: IS: 2386 (P-7) 1963
Clay Lumps and Friable Particles
Determines the percentage of particles that can easily disintegrate, ensuring material integrity under construction pressures.
Test Method: IS: 2386 (P-2) 1963
Soundness Test
Determines resistance to disintegration by freezing and thawing, providing information on the aggregate's resistance to weathering.
Test Method: IS: 2386 (P-5)1963
10% Fine Value
Ensures the aggregate meets a minimum strength valve, defining the required quality for construction projects.
Test Method: IS: 2386 (P-4)1963
Sand Equivalent Value
A rapid field test to show the relative proportions of fine dust or clay-like materials in fine aggregate.
Test Method: MORTM, IS: 2720 (Pt-37)1976, ASTM D 2419-2009
