Core Material Testing Services LLP

Fine Aggregate Testing Service ensures the quality, gradation, strength, and durability of sand and other fine aggregates used in concrete, asphalt, and construction projects. These tests verify compliance with IS 383, IS 2386, ASTM C33, AASHTO T27, and MoRTH standards, ensuring that fine aggregates meet the required gradation, shape, and strength specifications.

✅ Sieve Analysis (IS 2386 Part 1, ASTM C136, AASHTO T27) – Determines particle size distribution (gradation)
✅ Specific Gravity & Water Absorption (IS 2386 Part 3, ASTM C128) – Evaluates density & moisture absorption capacity
✅ Bulk Density & Voids (IS 2386 Part 3, ASTM C29) – Assesses compaction & void ratio
✅ Fineness Modulus (IS 2386 Part 1, ASTM C33) – Measures coarseness or fineness of sand
✅ Clay, Silt & Dust Content (IS 2386 Part 2, ASTM C117) – Ensures cleanliness & minimal impurities

✅ Crushing Value Test (IS 2386 Part 4, ASTM C131) – Determines aggregate strength under compression
