Lab Overview

Building Material Testing Room

Spacious testing room equipped with sieve shaker, specific gravity apparatus, bulk density cylinders, test sieves and vernier callipers — dedicated to coarse aggregate quality testing.

Gravimetric Testing

Specific Gravity & Water Absorption

Weighing 20 mm coarse aggregate sample (JKCW/OC/CA-02) on a calibrated Aczel precision scale for specific gravity and water absorption determination per IS 2386 (Part 3).

Sample Preparation

10 mm Aggregate Sample

Labelled 10 mm coarse aggregate sample (JKCW/OC/CA-01) spread in a tray — prepared for sieve analysis, flakiness, elongation and clay lump tests per IS 2386 (Part 1 & 2).

Shape Testing

Flakiness & Elongation Sorting

20 mm aggregate particles separated on a tray for flakiness and elongation index determination — key quality parameters per IS 2386 (Part 1).

SSD Weighing

SSD Condition — 20 mm Aggregate

20 mm coarse aggregate sample (JKCW/OC/CA-02) in Saturated Surface Dry (SSD) condition at 1508 g, ready for specific gravity and water absorption testing per IS 2386 (Part 3).
