NABL accredited testing for fine and coarse aggregates per IS 2386 at our lab on Bagalur Main Road, Yelahanka, Bengaluru.
Aggregates are the backbone of concrete — proper particle size distribution, strength, and cleanliness are essential. V2 offers a complete suite of aggregate tests: sieve analysis, specific gravity, water absorption, aggregate impact value, aggregate crushing value, flakiness index, elongation index, and more. Our NABL accredited lab performs tests per IS 2386 and related standards to ensure aggregates are suitable for structural concrete.
Our comprehensive testing covers all essential parameters required by Indian Standards and NABL protocols.

V2 Civil Diagnostics on Bagalur Main Road, Yelahanka, is a NABL accredited lab offering complete fine and coarse aggregate testing per IS 2386.
Fine aggregates (sand, M-sand) are tested primarily for gradation, silt content, and bulkage. Coarse aggregates (crushed stone, gravel) are additionally tested for impact value, crushing value, flakiness, and elongation — properties critical to concrete strength.
Coarse aggregate - Minimum 100 kgs sample required for all physical and chemical test. The exact quantity depends on the number of tests required.
Fine aggregate - Minimum 20 kgs for all physical and chemical test. The exact quantity depends on the number of tests required.
IS 383:2016 specifies grading requirements for coarse and fine aggregates used in concrete. Our reports compare your sieve analysis results against these limits.
Yes. M-sand is widely used in Bengaluru construction. We test it for gradation, silt content, specific gravity, moisture absorption, and bulkage per IS 2386.
Most physical tests for aggregates are completed within 3-5 working days. Sieve analysis and silt content results are typically available sooner.
NABL accredited results. Fast turnaround. Full regulatory acceptance.
