Jancy Labs — Trusted Aggregate Testing Lab
NABL Accredited Laboratory (Certificate No. TC-12176) as per ISO/IEC 17025:2017
Jancy Labs is a trusted aggregate testing lab in Madurai, Tamil Nadu. We conduct precise aggregate tests — including aggregate impact value test, sieve analysis, aggregate density, Los Angeles abrasion, flakiness and elongation index, and crushing value — to IS standards relied on by contractors, engineers, and government bodies across Tamil Nadu.
Why Aggregate Testing Is Important
Aggregates make up 60–80% of a concrete or asphalt mix by volume. A substandard aggregate — one that is too porous, too weak, or incorrectly graded — will compromise the strength and durability of the finished structure regardless of how well the cement or bitumen performs.
By independently verifying aggregate impact value, density, gradation, and hardness at a certified testing lab, builders and contractors confirm suitability for concrete, road construction, and other civil engineering applications — and satisfy the quality documentation required by government departments.
Tests in Our Aggregate Testing Lab
Our aggregate testing lab in Tamil Nadu conducts all standard IS tests for coarse and fine aggregates used in concrete, road construction, and civil engineering:
Aggregate Impact Value Test
The aggregate impact value test (IS 2386 Part 4) measures the toughness of aggregates by subjecting them to a series of impacts from a standard hammer. The impact value of aggregate is expressed as a percentage of fines produced — lower values indicate stronger, more impact-resistant material. This test is critical for road sub-base and base course materials.
IS 2386 Part 4Sieve Analysis (Gradation Test)
Sieve analysis (IS 2386 Part 1) determines the particle size distribution of aggregates for grading purposes — confirming whether coarse and fine aggregates fall within the specified zone or grading envelope for concrete mix design or road layer construction.
IS 2386 Part 1Los Angeles Abrasion Test
The Los Angeles abrasion test (IS 2386 Part 4) evaluates aggregate hardness and resistance to wear and degradation under mechanical action — an essential quality parameter for aggregates used in high-traffic road pavements and concrete structures.
IS 2386 Part 4Aggregate Density & Water Absorption
Specific gravity and water absorption tests (IS 2386 Part 3) assess aggregate density and porosity. Aggregate density directly affects concrete mix design proportioning and unit weight calculations, while water absorption influences the effective water-cement ratio and workability in the final mix.
IS 2386 Part 3Flakiness & Elongation Index
The flakiness and elongation index test (IS 2386 Part 1) determines the shape characteristics of aggregate particles. Excess flat or elongated particles reduce compaction efficiency, increase water demand, and weaken concrete or asphalt mixes — making this test a key acceptance criterion for road and concrete aggregates.
IS 2386 Part 1Aggregate Crushing Value Test
The aggregate crushing value test (IS 2386 Part 4) identifies the strength and resistance of aggregates to crushing under a gradually applied compressive load. This is a mandatory quality test for aggregates used in road base and sub-base courses, and for structural concrete elements.
IS 2386 Part 4Aggregate Lab Tests at a Glance
All aggregate tests at Jancy Labs follow the IS 2386 series of standards. Below is a quick reference covering the key parameters tested:
| Test | IS Standard | Parameter Measured | Application |
|---|---|---|---|
| Aggregate Impact Value Test | IS 2386 Pt 4 | Impact value of aggregate (% fines) | Road base, sub-base, concrete |
| Sieve Analysis | IS 2386 Pt 1 | Particle size distribution, grading zone | Concrete mix design, road layers |
| Los Angeles Abrasion Test | IS 2386 Pt 4 | % wear, hardness under mechanical action | Road pavements, structural concrete |
| Specific Gravity & Water Absorption | IS 2386 Pt 3 | Aggregate density, porosity, absorption % | Mix design proportioning |
| Flakiness & Elongation Index | IS 2386 Pt 1 | Shape factor of aggregate particles | Road & concrete aggregate acceptance |
| Aggregate Crushing Value | IS 2386 Pt 4 | Crushing strength under compressive load | Road base course, structural concrete |
Why Choose Jancy Labs' Aggregate Testing Lab?
At Jancy Labs, we provide accurate, comprehensive, and timely aggregate testing services that builders, contractors, and consultants across Tamil Nadu rely on:
Accurate Results
Our state-of-the-art equipment and experienced professionals ensure precision in every test — from aggregate impact value to sieve analysis and aggregate density measurement.
Comprehensive Testing
We cover all standard and advanced aggregate tests to meet your project needs — both coarse and fine aggregate properties — from a single lab location in Madurai.
Timely Reports
Our efficient processes guarantee quick turnaround times without compromising quality — ensuring your project schedule is not delayed waiting for test results.
Customer-Centric Approach
We work closely with clients, offering personalised solutions and expert guidance — from sample submission to report interpretation and compliance advice.
Who Should Test Aggregates?
Builders, contractors, and engineers involved in construction projects should prioritise aggregate testing before materials reach the site. Government agencies and project consultants overseeing infrastructure developments must also ensure compliance with quality standards.
Testing aggregates is not only a best practice — it is a requirement for meeting industry regulations. A single batch of substandard aggregate that bypasses testing can compromise an entire concrete pour or road base course, resulting in costly remediation that far exceeds the cost of a test.
